The PWM signal in question is fed through a piezo speaker in parallel with a resistor. The output from the speaker is then sent to an FFT (fast fourier transform) app for Android devices ...

Fan sizes and speeds impact noise output, with smaller ... and maintains optimal PC temperatures. PWM stands for Pulse Width Modulation, which is a type of signal used to control electronics.

The advantage is the output capacitor gets a kick more often and has less opportunity to droop. You probably want a scope to measure PWM or pulse density, but we’ve talked about how to do it ...
