Abstract :
A new method of designing nonrecursive quadrature mirror filters with small deviation from the desired overall response is described. By imposing linear constraints at the midpoint of the filter frequency scale, in addition to the normal passband and stopband constraints, a solution that is very close (doubt) optimum is obtained. Satisfactory designs can thus be obtained without resorting to techniques involving the solution of nonlinear constraints. Some results of practical interests are presented.
