Answer: What is Quadrature Mirror Filter mean?

In digital signal processing, a quadrature mirror filter is a filter whose magnitude response is the mirror image around π / 2 {\displaystyle \pi /2} of that of another filter. Together these filters, first introduced by Croisier et al., are known as the Quadrature Mirror Filter pair.

A filter H 1 ( z ) {\displaystyle H_{1}(z)} will be the quadrature mirror filter of H 0 ( z ) {\displaystyle H_{0}(z)} if H 1 ( z ) = H 0 ( − z ) {\displaystyle H_{1}(z)=H_{0}(-z)}

The filter responses are symmetric about Ω = π / 2 {\displaystyle \Omega =\pi /2}

| H 1 ( e j Ω ) | = | H 0 ( e j ( π − Ω ) ) | {\displaystyle |H_{1}(e^{j\Omega })|=|H_{0} reference
