WebA time–frequency representation ( TFR) is a view of a signal (taken to be a function of time) represented over both time and frequency. [1] Time–frequency analysis means analysis into the time–frequency domain provided by a TFR. This is achieved by using a formulation often called "Time–Frequency Distribution", abbreviated as TFD. You can divide almost any time-varying signal into time intervals short enough that the signal is essentially stationary in each section. Time-frequency analysis is most commonly performed by segmenting a signal into those short periods and estimating the spectrum over sliding windows. The pspectrum function used … See more Even though we have been able to identify four frequency ridges, we can still see that each ridge is spread over several adjacent frequency bins. This is due to the leakage of the windowing … See more Consider the following recording, consisting of a chirp signal whose frequency decreases over time and a final splat sound. Let us reconstruct a portion of the "splat" sound by … See more In certain applications, it may be preferable to visualize the spectrogram of a signal on a logarithmic frequency scale. You can achieve this by changing the YScale property of the … See more Consider a complex linear frequency modulated (LFM) pulse, which is a common radar waveform.
