MAKING LOW PASS FILTER

alsalamo alekom

can you tell me how can i make a low pass filter that can be used in recieving signals
with circut drawing please

I advise that you try MicroCUP v7 simulator for this purpose.
The program has a build-in analog filter design tool which is very friendly & easy to use. There are also some sample circuits.

http://www.aade.com/filter.htm is a free LC filter design program.

You will need to know beforehand what frequency range you want to pass, what range to attenuate and by what amount, the load impedance and the soruce impedance.
