Square wave audio amplifier test vs a sine wave.
Ah, I think I get it.
The square wave has all the odd harmonics, so your 300Hz square is like simultaneously putting sine waves at 300, 900, 1500, 2100, 2700, 3300, ... (at decreasing amplitudes) through the amp.
So you're testing the amp over a wide range of frequencies at once, but also seeing if there's interferences / interactions between those frequencies within the amp.
Is that right?
