MTX Audio

Hi,

This amp has all the wave forms and also square wave on one side of inductor but other side no sinewave at all. Picture of the amp attached. Sinewave is reaching driver board.

Modulation is when a square wave changes pulse width in relation to the input signal. With no modulation, it's a clean square wave. With modulation, it's mostly blurred.

This is a power supply being modulated. It's different because it's always less than 50% but you get the idea. It's only 640x480 resolution so if viewed full screen, it looks awful.

There is no modulation. It is just a square wave 110khz frequency.
