Abstract
The multiplier according to the invention comprises N shift registers (RD.sub.O, . . . , RD.sub.N-1) containing the words x.sub.i on B bits, N conditional adders (AdC.sub.O, . . . , AdC.sub.N-1) each adding to the partial sum which they receive a constant coefficient (a.sub.1), conditional on the value of the bit (x.sub.i,j) which they receive from the associated register (RD.sub.1) and an adder accumulator (AdAc). The digital filter using such a multiplier also comprises a parallel word input register.
