Hi
I am working on Digital Filters , I am facing a problem in giving the input to a bandpass filter and observing that in scope at the output. Initially i found that there is no digital signal to give directly to the Filter block and secondly I want to observe the output wave form for that i require a DAC. So i have to build a system with the following blocks
1.Sine wave ( its there in sources )
2. ADC ( it is there in discrete section)
3. Digital Filter ( bandpass)
4. DAC ( dont know where i can get )
5. Scope ( i found it)
or is there any other option to scip 1st two blocks in the above mentioned sequence.
Thanks & Regards

Dear friend;
You want to do it in some kind of simulation or want to process real world signals.
for real world signals you can use your PC mic input, have a look at links;

Hi
Thank you but i want a digital signal directly in matlab

Thank you but i want a digital signal directly in matlab

So in other words you want to simulate the entire process within Matlab using Simulink, is that correct?

Yes exactly
