PURPOSE:To reduce an operation scale by relating input signals with internal variables and by expressing output signals with these internal variables. CONSTITUTION:N-number input signals Xn sampled by period T are multiplied by coefficient matrix 1/B1 of size N through adder 22 in the first matrix operator 23, and output Un (internal variable) is delayed by time NT in delay equipment 28. Output Un-N of delay equipment 28 is supplied to the second matrix operator 29 and is multiplied by coefficient matrix B2 of size N and is supplied to adder 22. Further, input and output signals Un and Un-N of delay equipment 28 are supplied to the third matrix operator 37, and the output multiplied by coefficient A1 from terminal 40 and the output where the output of the first matrix operator 23 is multiplied by coefficient a0 in multiplier 38 are added by adder 39 to take out output signal Yn. Consequently, only three matrix operations dependent upon the first to the third matrix circuits 23, 29 and 37 are required. |
