Abstract :
A general structure of M band N channel multifilters is presented. The aliasing cancellation condition and perfect reconstruction condition are derived. The structures and properties of multifilters constructed by paraunitary matrices are discussed. Time domain design method using quadratic constraints is proposed. Design example of paraunitary multifilters is presented
