Abstract
PURPOSE: To make an input analog waveform and output analog waveform alike without increasing the capacity of a memory by correcting a difference in phase between the input and output waveforms.
CONSTITUTION: Memory 19 is stored with quantized analog signals. Subtracter circuit 22 calculates a difference in quantized data between address (m) and address m+1 of memory 19. Divider circuit 23 divides the above-mentioned subtraction result by (n). Synchronizing with the read timing of memory 19, 1st gate circuit 27 allows quantized data of address (m) in memory 19 to pass through. At every timing one (n)-th the read timing of memory 19, 2nd gate circuit 33 allows the output of divider circuit 23 to pass through. Adder circuit 34 adds the output of divider circuit 23 to that of the 2nd gate circuit. Then, D/A converter 36 receives the output of adder circuit 34. Smoothing circuit 37 smooths the output of D/A converter 36.
