Abstract

PURPOSE:To reduce nonlinear distortion generated in a multiplier, having the number of bits limited, in a digital filter only by adding a simple circuit. CONSTITUTION:A digital signal (m bits) arriving at input terminal 1 is supplied via input register 2 to delay unit 10, where it is delayed by not less than one sampling cycle, and its output is applied to shift register 14, which shifts it with shift pulses from detecting controller 11 in the MSB(most significant bit) direction to output an n-bit digital signal to multiplier 4. Here, it is multiplied by an n-bit digital signal from coefficient unit 3 to supply shift register 15 with a 2n-bit digital signal. Shift register 15 shifts the input in the LSB(least significant bit) direction with shift pulses from detecting controller 13 and an m-bit digital signal is obtained again and then applied to input terminal A of adder 5.
