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 ...

The IC’s built-in soft clipping will limit the volume gain, but we’ll get something that’s ever more like a square wave as we keep passing the signal through further amplification stages.

Spruce trees anticipated a solar eclipse by syncing their signals. Older trees responded first. Forests may behave as one ...
