Abstract
A wave digital filter wherein structures are specified such that the transfer function (Y/X) can be arbitrarily prescribed. The filter input signal X--individually weighted via multipliers (E.sub.1 . . . E.sub.x)--is input at all adaptor inputs and outputs with adders. The filter output signal Y is formed by summation of the signals weighted via further multipliers (A.sub.a . . . A.sub.y) which are output at all adapter and delay inputs and outputs.
