What does the de-emphasis network correct?
Answer: D
It undoes the transmitter's treble boost and in doing so attenuates the noise that rose with frequency, which is the net gain in signal-to-noise ratio the pair delivers. Discriminator nonlinearity is a design matter. Filter phase error is corrected, if at all, by filter selection. And residual amplitude variation is the limiter's problem. The pair must be matched end to end, which is why the European and North American time constants cannot be mixed.
