Abstract

PURPOSE:To find a filter output value only by addition by transforming a function of variables ZoM, Z1M...Zn-1M in the 1st term showing subtraction into a constant and by storing and drawing the constant in and out of a storage device. CONSTITUTION:When five-dimensional vector (xn<j>, xn-1<j>, xn-2, yn-1<j>, yn-2<j>) supplied is not equal to the zero vector, psi<j> is drawn out of storage device MEM2 and stored in register R1. When vector (xn<j>, xn-1<j>, xn-2<j>, yn-1<j>, yn-2<j>) is equal to the zero vector, on the other hand, the contents of register R1 is cleared with a clear signal, low-level signal, from OR element OR. Then, psiM<+1> drawn out of device MEM2 is supplied to adder AD via register R1 and then added to the last output psiM of adder AD stored in register R2 over a shift, finding filter output value yn.
