Abstract
PURPOSE: To prevent oscillation caused by feeding a feedback signal to an adder without any restriction, by providing an intermediate register to the feedback loop of an adder which adds sequentially an output digital signal value before feedback to an input digital signal value.
CONSTITUTION: Electronic switch SW, having terminals 11 to 1n, are circularly connected by switching to apply digital signals to adder 2 in sequence. Its output F is applied to output register 4 and retained there by control pulses from terminal 5 while applied to total register 6. Intermediate register 9 maintains output signal R of output register 4 and fixes the value of digital signal Q of the 2nd input terminal of adder until output register 4 receives and holds the value of output F of adder 2.
