Abstract
PURPOSE:To reduce the burden of a filter circuit, by alternately giving an average output between the present data and the data before by one and the data before by one itself. CONSTITUTION:The output data of an audio synthesizer 10 is read in the 1st register 11 with the clock P1 in 8kHz, and the output data of the register 11 is read in to the 2nd register 12 with clock P2 in 8kHz. The output data of the registers 11, 12 is given to an interpolation circuit 13 and the data averaged with both the data is outputted. Switches 14, 15 are turned on and off by complementary clocks P14, P15 which rise every 62.5mus (16kHz), and the output data of the register 12 and the interpolation circuit 13 are alternately given to a D/A converter 16. No 8kHz component is present at the output of the converter 16.
