for Class-D amp, if there are 2 signals (with different frequency and different levels and combined) inputs, what happens at the outputs, after the LPF, can we still see that 2 whole signals.

or what happens after the comparators.

compare the signal level within the input signal and the triangle wave, if there are 2 signals inputs, and both of them the level is high than the triangle, so, the one signal will be ignored, is it right.

maybe it is a stupid question, looking for the answer.
