A Quadrature Mirror Filter (QMF) is a type of digital filter that is commonly used in signal processing, particularly in applications like subband coding, audio compression, and wavelet transforms. The primary purpose of a QMF is to split a signal into two frequency bands, typically low and high frequencies, in such a way that the original signal can be perfectly reconstructed when these bands are combined.
