Digital Signal Processing

This library is focused in working with block of data not on real time processing.

If you are looking for a realtime processing library then there is already great library for it https://github.com/FutureSDR/FutureSDR

The folder examples contains demo programs which shows how to use this library.

Features

Signal generators

Signals generators are nodes with the state. This allows to generate continuos signal across multiple buffers. Implemented generators:

• Impulse
• Step
• Sinusoid
• Triangle
• Square
• Chirp
• Noise

Filters

• Biquad
• Leaky Integrator (Exponential Smoothing)

Window functions

• Rectangular
• Triangular
• Welch
• Sine
• Hann
• Hamming
• Blackman

Frequency domain

• FFT forward and inverse using RustFFT crate.
• Find peak frequency

Time domain

• Frequency shifter
• FM demodulation
