... displacement of the water, and so on. The shape of the time domain waveform is not importantin these signals; the key information is in the frequency, phase andamplitude of the component sinusoids. The ... ispresent. In other words, the length of the signal limits the frequencyresolution. This is distinct from the first factor, because the length of the input signal does not have to be the same as the length ... Fig. 9-9d and examine the center period, samples 256 to 511. Since all of the periods are the same, the portion of the signal that flows out of this period to the right, is the same thatflows...
