In time-frequency analysis, a signal is analyzed as a function of both time and frequency. Thus, in contrast to one-dimensional time domain and frequency domain representations, the signal is represented in a two-dimensional space.
Time–frequency analysis comprises those techniques that study a signal in both the time and frequency domains simultaneously, using various time–frequency ...
