2021-11-1 · The “balance” of the tone generator circuit must be carefully adjusted to regulate the amplitudes of the two audio signals in a manner that the cross section centering the waveform is as sharp as possible. Then the two audio signals are nearly 100% equal which will result in the demonstrated signal amplitude waveform.
