Hi Pradeep I have transmitted some pulses corresponding to a Morse code pattern. e.g, if the code is ..---.-.---.-- then '.' will have a particular frequency pulse and '-' will have a particular frequency pulse. Thus it is a stream of pulses having two frequency. you can clearly understand that

Hi Soumyajit, Can you clarify on a few things on your need, for example: what's the input source for the sound pulses that you will be getting, because If its a hardware connected to your device then I guess your device would need to be interfaced with linux kernel. If the sound pulses are stored
