The spectrum of a chirp pulse describes its characteristics in terms of its frequency components. This frequency-domain representation is an alternative to the more familiar time-domain waveform, and the two versions are mathematically related by the Fourier transform. The spectrum is of particular interest when pulses are subject to signal processing. For example, when a chirp pulse is compressed by its matched filter, the resulting waveform contains not only a mai… WebChirp Signal in MATLAB 5,281 views Oct 20, 2024 Share Save IntellCity 4.66K subscribers In this video, we will show you an easy way to generate and plot a Chirp Waveform Signal in MATLAB.... simplifying summations
