The Fast Fourier Transform (FFT) is a powerful tool for analyzing signals in the frequency domain. Python and SciPy provide an easy way to perform FFTs. To use SciPy, the following code can be used: ...
There are Jupyter Notebooks that show how to use both the static plotting and animated methods using both generated data, in the form of a QPSK signal, and RTLSDR captures. The full description can be ...
(load "fft/fft_demo.lsp") ;; you must load the code before calling functions (hp-test) ;; simple high-pass by zeroing low frames (mod-test) ;; FM cross-synthesis (mod ...
