A common practice is to sample the frequency spectrum of the sampled data at frequency intervals of f s /N, for some arbitrary integer N (see § Sampling the DTFT).The samples (sometimes called frequency bins) are numbered consecutively, corresponding to a frequency normalization by f s /N.: p.56 eq.(16) … Ver mais In digital signal processing (DSP), a normalized frequency is a ratio of a variable frequency (f) and a constant frequency associated with a system (such as a sampling rate, fs). Some software applications require … Ver mais A typical choice of characteristic frequency is the sampling rate (fs) that is used to create the digital signal from a continuous one.
