Struct sdr::cic::CIC

pub struct CIC<T: SampleType> { /* fields omitted */ }

Qth order CIC filter with decimate-by-R (and D=R).

Methods

impl<T: SampleType> CIC<T>

pub fn new(q: usize, r: usize, bw: usize) -> CIC<T>

Create a new CIC filter of order q and downsampling ratio r.

Bitwidth is the number of bits actually used by your input data, so must be equal to or less than the size of the data type.

Note that bitwidth + ceil(Q log2 R) must <= 32.

pub fn process(&mut self, x: &[T]) -> Vec<T>

Run the CIC filter over a block x, returning the filtered and decimated output.
