use cic_fixed::CicDecimationFilter;

let mut filter = CicDecimationFilter::<4, 2>::new();
let result = filter.process_sample(&0);
assert!(result.is_none());
let result = filter.process_sample(&1);
assert!(result.is_none());
let result = filter.process_sample(&2);
assert!(result.is_none());
let result = filter.process_sample(&3);
assert!(result.is_some());
assert_eq!(result.unwrap(), 10);
