... the computational requirement to make convolution is very large. In fact, for 100.000 input samples, for every output sample to be computed, 100.000 products and 100.000 sums are required! Instead, passing to the frequency domain, the operation is just a multiplication, so we reduce the computationa ...

... enough if the signal always used the full range. But signal varies in loudness. If full range is used for loud parts, quiet parts will suffer from bad quantization noise (only a few levels used). If full range is used for quiet parts, loud parts will clip, resulting in really bad noise. CD uses ...

guided media (twisted pair, coaxial cable, and optical fiber)
... Delay distortion: occurs in guided media. It is caused by the fact that the velocity of propagation of a signal through a cable is different for different frequencies. For a signal with a given bandwidth, the velocity tends to be highest near the center frequency of the signal and to fall off towa ...
