Real-time data acquisition from Arduino over serial and frequency analysis using the Fast Fourier Transform (FFT). Built as a practical signal processing toolkit for embedded sensor systems. Captures ...
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 ...
