That is, the signal is an infinite-extent cosine multiplied by a finite-extent rectangular …
WebUsing the Fourier transform, you can also extract the phase spectrum of the original signal. For example, create a signal that consists of two sinusoids of frequencies 15 Hz and 40 Hz. The first sinusoid is a cosine wave with phase -π / 4, and the second is a cosine wave with phase π / 2. Sample the signal at 100 Hz for 1 second.
