Abstract
A digital circuit which receives a serial input signal and which suppresses fast signal variations. The digital circuit includes an integrator circuit (1) which generates a multi-bit signal by integration of the serial input signal. The output signal of the integrator circuit is applied to an evaluation circuit (2) which generates a serial output signal which assumes a first state when the multi-bit signal exceeds a first threshold value and a second state when the multi-bit signal is below a second threshold value.
