Half-band filter - Wikipedia

WebHalfband filters are widely used in multirate signal processing applications when interpolating or decimating by a factor of two. Halfband filters are implemented efficiently … In digital signal processing, half-band filters are widely used for their efficiency in multi-rate applications. A half-band filter is a low-pass filter that reduces the maximum bandwidth of sampled data by a factor of 2 (one octave). When multiple octaves of reduction are needed, a cascade of half-band filters is common. And when the goal is downsampling, each half-band filter needs to compute only half as many output samples as input samples. WebA half-band filter is a low pass filter that reduces the maximum bandwidth of sampled data by an approximate factor of 2 (one octave). When multiple octaves of reduction are … eyes that water
