Chirp signal python code

WebThis example shows how PyTFTB is used to generate a signal with linear frequency modulation. Such a signal is also called a chirp. Figure 1.1 from the tutorial. from … WebHere we generate a mixture of two Gaussian-modulated chirp signals, with gradually increasing frequencies starting from 5Hz and 40Hz, respectively. The resulting signal is shown below. The STFT results is also illustrated below.
