Maria Kastemaa, 2015 02 14: Hello, I'm getting started with the second edition of the DSP book, and finding it very clear and well structured so far. :) I did spot a couple of issues however:

On page 10, the fact box says "The term bit rate is also used to mean sampling resolution" — I think this should be bit *depth* rather than bit rate, which measures bits per units of time (and for stereo CD audio would be 2*44100*16 b/s = 1411200 b/s).

On page 24, the definition of RMS amplitude has an off-by-one error: as the sum x(0)² + x(1)² + … + x(N)² is indexed by 0…N, the number of samples is N+1 instead of N as stated.
