This is a relatively slow place, so if you don't feel like interpretation the total phenomenon, fair scroll to the halt and read the TL;DR section. I was on vacation in Vermont final week, at some point in demo Break. We went skiing near. I've additionally been working on a a small amount electronics project. I've by no means made no matter which like it in the past, until in a jiffy I've been in performance around with circuits on breadboards. This is the in the beginning electronics project I've prepared to has a doable claim.

So come again? This device chooses which HDMI input self-control be there connected to the output. I make use of both of them with my HDTV. So I can wish which solitary is departure to the tube next to the bit of a button, lacking having to switch up several cables when I aspire to use individual of them and the other happens to remain plugged in. It isn't finished.

Indeed, it's still arrived the planning stage. I have a schematic drawn, but I won't stake it yet for the reason that it's partially-finished! Therefore, calculating parasitics in this circuit is essential. To stay decent, I don't know could you repeat that?

That's a different occurrence I'll partake of to numeral old hat This is made much easier for the reason that the kind relatives on electronics have pointed me dressed in the perfectly direction! But I know so as to I can't create a controlled importance of it on a breadboard. So, I'm going away to have to fritter lots of moment in time on the planning stage, since if I order parts and comprehend a PCB fictitious, and I made a misstep, with the aim of's money and time down the drain for the reason that therefore I maintain to order a innovative PCB and maybe new components too.

So, give permission's possibility it machinery! And even if it doesn't, it preference ensue a huge learning experience.

This project will affect shell-mount soldering, PCB design and ordering, brainwashing an AVR microcontroller playing piece, and supplementary. And all of persons things I have by no means made already.Sometimes also called a Data Selector.

A circuit that transmits one of two or more signals from the input to the output. A multiplexer would be considered standard logic or glue logic when a discrete IC is used.

Multiplexers by Function: Note in most cases when a 74xx device is listed, a 54xx device is also available. However the components below appear to be in current production.

These design rules help with Logic to Logic Translation. Editor note; I'm not all that clear of the difference between a data selector and a multiplexer. Of course the design, or the number of product shipped would need to support the cost of an FPGA costing hundreds as opposed to a 20 cent decoder.

The point being that many circuit designs no longer use small scale integrated circuits in their designs, when an FPGA is already present in the circuit. Editor note; The DOD specifications are listed as a reference only. Because the military controls the documents, they could be withdrawn from usage at any time. In fact since the mid 's the government has slowly been reducing the number of documents in circulation.

So, each combination will select only one data input. Multiplexer is also called as Mux. The block diagram of 4x1 Multiplexer is shown in the following figure. One of these 4 inputs will be connected to the output based on the combination of inputs present at these two selection lines.

Truth table of 4x1 Multiplexer is shown below. The circuit diagram of 4x1 multiplexer is shown in the following figure. We can easily understand the operation of the above circuit.

Similarly, you can implement 8x1 Multiplexer and 16x1 multiplexer by following the same procedure.

Now, let us implement the following two higher-order Multiplexers using lower-order Multiplexers. In this section, let us implement 8x1 Multiplexer using 4x1 Multiplexers and 2x1 Multiplexer. We know that 4x1 Multiplexer has 4 data inputs, 2 selection lines and one output. Whereas, 8x1 Multiplexer has 8 data inputs, 3 selection lines and one output. So, we require two 4x1 Multiplexers in first stage in order to get the 8 data inputs. Since, each 4x1 Multiplexer produces one output, we require a 2x1 Multiplexer in second stage by considering the outputs of first stage as inputs and to produce the final output.

The Truth table of 8x1 Multiplexer is shown below. We can implement 8x1 Multiplexer using lower order Multiplexers easily by considering the above Truth table. The block diagram of 8x1 Multiplexer is shown in the following figure.

The outputs of first stage 4x1 Multiplexers are applied as inputs of 2x1 Multiplexer that is present in second stage. The other selection line, s 2 is applied to 2x1 Multiplexer.

Therefore, the overall combination of two 4x1 Multiplexers and one 2x1 Multiplexer performs as one 8x1 Multiplexer. In this section, let us implement 16x1 Multiplexer using 8x1 Multiplexers and 2x1 Multiplexer.

We know that 8x1 Multiplexer has 8 data inputs, 3 selection lines and one output. Whereas, 16x1 Multiplexer has 16 data inputs, 4 selection lines and one output.

So, we require two 8x1 Multiplexers in first stage in order to get the 16 data inputs. Since, each 8x1 Multiplexer produces one output, we require a 2x1 Multiplexer in second stage by considering the outputs of first stage as inputs and to produce the final output. Let the 16x1 Multiplexer has sixteen data inputs I 15 to I 0four selection lines s 3 to s 0 and one output Y. The Truth table of 16x1 Multiplexer is shown below.

We can implement 16x1 Multiplexer using lower order Multiplexers easily by considering the above Truth table. The block diagram of 16x1 Multiplexer is shown in the following figure.The device can take any one of four audio inputs, pass the signal through an amplifier, and send it to any one of four outputs.

The audio amplifier has a volume control, and the inputs and outputs can be selected via button presses. An Arduino Pro Mini takes care of switching the relays based on the button presses. On the input side, you can plug in devices like a phone, TV, digital audio player or a computer. The output can be fed to speakers, headsets or earphones. This audio op-amp is designed to drive 32 ohm loads, so performance might suffer when connecting it to lower impedance devices, but it seems to work fine for headphones and small computer speakers.

The dual-gang potentiometer controls the volume, and the chip has a useful de-pop feature. The circuit is pretty much a copy of the reference shown in the data sheet. As he says, always double-check part footprints! In the end, he solder-bridged them on to the board, but they should probably be fixed for the next revision.

And who would need 4 selectable outputs? I would be happy with two outputs: one for headphones and one for PA. Most of the times throwing a bigger MCU is the cheapest solution, especially in a 1 of circuit when you consider the time.

A dumb split yields 11 audio ports for his enjoyment using his current design choices. Great work winslomb! I am really curious what is the effect of the SSR on the output signal…. Any analysis? There are much analog mux that are designed for routing audio signals. I want to user a Raspberry to switch between three audio input sources to an amp that has only one input. Point me in newbie language to some components to use for this please.

Simpler and cheaper is better. Would the MAX mentioned above be a match for this task?

If not what would? An advanced bonus feature would be to somehow have it sense when there is audio input coming in only one of the three inputs and then automatically direct that input into the amp. Just grab a board with 2 DPDT relays i assume stereo sources.

One relay selects source 1 or 2, the second relay selects source 3 or relay 1, thus you have a 3 input selector. Mixers are great for this task on the input side, and a speaker switch on the amp. This has to be done with resistors mixing usually. My computers are in series with the final sounds going to a simple 4 channel mixer along with the radio often on and a cassette deck. I need to stuff a preamp into the turntable, then it could be the fourth line level input.
