I need to make a system which generates, at least, 14 distinsts waveforms.

I know I have to use a multiplexer and a clock signal in the system.

However, which IC, should I use? How can I make this system works?

Thanks

 

How are we supposed to help you with such limited information?
What are the 14 distinct waveforms (amplitude, frequency, shape, etc.) you need.
Can this system use a commercial pulse generator?
What is this for?

 

Think of how useful (meaning useless) is the title of your thread.
A better title would be:

How to generate 14 different waveforms?

 

Is this homework?

You typed this on a computer, right? My computer (or my phone) can generate waveforms. I bet your's can too.

Not good enough? Perhaps you could share what other hidden specifications you have in mind.

Why do you think you have to use a multiplexer or a clock signal in the system?

You could use a PIC12F1501.

How can I make this system works?

By designing a suitable circuit using a PIC12F1501 and writing a suitable program to run on a PIC12F1501.

Thanks

You're oh so welcome.

 

Can 800KHz, 400KHz, 200KHz, 100KHz, 50KHz, 25KHz, 12.5KHz, 6.25KHz, 3.125KHz, 1562Hz, 781Hz, 390Hz, 195Hz, 97Hz square waves be considered as 14 distinct waveforms?

Please help me

I need to make a circuit which generates, at least, 16 distinsts waveforms(change the frequency or the length)
I have to use a multiplexer with 16 differents outputs, a counter and a 5Hz clock.
I need also to change the output wave by switching the keys and put a LED in the output. (See the attachment)

I've already done the clock using an IC 555 and I've tried to build this circuit with the multiplexer and the counter, but it doesn't work.

I will attach my current circuit and how should be my outputs(there´s only 4 in the picture I need to make 16 differents waveforms).

What changes should I make?

Thanks for your help!

Any microprocessor. Waveforms attached.

Another possibility, an XR2206 or such waveform generator and a bunch of op amps that mix the outputs together, then you could use your analog selector to select one. Data sheet and source attached.

so many possibilities.

But I have to use a multiplexor and a counter uskng the program Multisim

I see a counter, 74190. Multisim libraries are pretty slim. I prefer using ORCAD for making schematics. There is a free version very rich in libraries.

 

Hints:
You could use cascaded binary counters to get your 16 different waveforms.
A problem with your circuit is that when the key switches are open the D inputs of U1 (a TTL device) default to logic high.
