Struct CicDecimationFilter 

pub struct CicDecimationFilter<const M: usize, const N: usize> { /* private fields */ }

CIC decimation filter.

• M - Decimation factor
• N - Number of stages

Implementations

impl<const M: usize, const N: usize> CicDecimationFilter<M, N>

pub const fn new() -> Self

pub fn process_sample(&mut self, input: &i32) -> Option<i32>

Process the input and return the output when the decimator is ready to output a value.

Arguments

• input - The input to filter.

Returns

The output of the filter.
The output range is Input range * (M^N). For example, if Input range is +/-1, M is 4, and N is 2, the output range is +/-16.
When the decimator is ready to output a value, it will return some(input). Otherwise, it will return None.

pub const fn bit_growth(&self) -> u32

Returns the number of bits increased by passing through the CIC decimation filter.
The bit increase by the CIC decimation filter can be expressed by the following equation.
log2(M)*N
M is the decimation factor and N is the number of stages.
