Abstract
PURPOSE: To smoothen the variation in digital signals by interpolating input signals with the use of the up- and down-counters which are operative to generate the counted values having more bits than that of the input signals.
CONSTITUTION: The input digital signals of five bits or the like are compared by a comparator 1 with the upper five bits more than the input signals of ten bits, which are generated by such an up-down counter 3 as is operative to count the high frequency output from an oscillator 5. In accordance with the comparison, the comparator 1 controls the counter 3 to the down-up counting operations to interpolate the input signals. If the comparison reveals coincidence, the comparator 1 stops the counter 3. By the output of the counter 3 at this time, the five bit signals are interpolated into the converted ten bit signals so that variation in the digital signals is smoothened by the increase in the bit number. As a result, if the musical signals are generated by the system thus disclosed, accurate signals can be generated with the use of a simple construction.
