Title: Digital roll-off filter
Inventor: TAKI YOSHIHIKO
IPC: H03H15/00
Filed: 1992-09-24
Abstract: PURPOSE:To reduce the circuit scale through the reduction in number of multipliers and to prevent the deterioration in the processing by eliminating n-sets of one side multipliers for a center position and instead applying outputs of the n-set of multipliers on the remaining side to an adder at a position symmetrical for the center position. CONSTITUTION:Each output from multipliers 311-31n is branched into two, one of them is fed respectively to adders 332n-33n+1. Thus, an output of the adder 33n is delayed by a unit delay element 32n+1 and added to an output of the multiplier 31n by an adder 33n+1 and fed to a next unit delay element 32n+2. Similarly an output of a unit delay element 322n-1 and an output of the multiplier 312 are added by an adder 332n-1 and its output is delayed by a unit delay element 322n and added to an output of the multiplier 311 by the adder 332n and output data y(n) are outputted from a terminal 34. Thus, outputs by (2n+1) sets of multipliers of a conventional filter are outputted by using (n+1) sets of multipliers 311-316+1.
