The “sampling theorem” says that, if the sampling frequency is more than twice as high as the maximum frequency of original signal, then the original signal can be retrieved by A/D and D/A conversion. With CDs, the sampling frequency is 44.1kHz, meaning the maximum frequency is band-limited to 22.05kHz. Therefore, the information on the waveform for over- 22.05kHz frequencies is not transmitted.

Unless it’s sinusoidal, a signal contains multiple high-order harmonics. So does a square wave. If the input is a 1kHz square wave signal, it retains its shape because much of the information on the waveform for harmonics is retained after the A/D and D/A conversion. But if the input is a square wave of a high frequency, the converted signal presents

a rounded shape because of the absence of information on high frequencies.
