Pulse counting works by generating a narrow, fixed-width square wave pulse at a set point in the received FM signal’s waveform, usually at the zero-crossing point. Since the frequency of the ...

Expose overlapped transactions. Unlike signal waveforms, transactions are often overlapped. Waveform tools have to provide a mechanism to bring “hidden” transactions to the front. View Detailed ...

The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM ...
