Abstract

PURPOSE:To enable mixing less in distortion and noise, by direct operation of digital signals. CONSTITUTION:The input analog signal is input to the input terminals 3a, 3b and required signal is digitized at the A/D converter via the switching circuit. The digitized signal input is fed to the digital tone control circuit 18 and after required frequency characteristics are given, it is fed to the digital signal mixing operation circuit 19. When the characteristics A of mixing circuit are determined to the input signal VI, the output signal V0=AXVI can be obtained. The digitized value of the mixing characteristics A is produced at the matrix element decision circuit 20 and it is fed to the digital signal mixing and operation circuit 19. Since the digital signal mixing and operation circuit 19 can be executed with the matrix operation in digital value, the constitution can be simpler.
