pub struct Fft { /* private fields */ }
Expand description
Computes an FFT
This block computes the FFT on len
samples at a time, outputting len
samples per FFT.
Inputs
in
: Input samples (Complex32)
Outputs
out
: FFT results (Complex32)
Usage
use futuresdr::blocks::Fft;
use futuresdr::runtime::Flowgraph;
let mut fg = Flowgraph::new();
let fft = fg.add_block(Fft::new(2048));
