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 ...

According to SurfLoch: “We create ‘swell’ from intense and precise air management using both vacuum and pressure to create a wave pulse. This wave pulse exits the wave chamber and propagates ...

send out a radio wave and time how long it takes to get back via an echo. However, in practice, there are a number of trade-offs to consider. For example, producing a long pulse has more energy ...
