Abstract

A method for suppressing a spurious pulse following a measurement pulse in a measurement signal using a circuit includes generating a square-wave signal from the measurement signal. A delayed square-wave signal is generated by delaying the square-wave signal by a time span τ. The delayed square-wave signal is input into a control input of a switching arrangement. The measurement signal or a signal derived therefrom is input into an input of the switching arrangement. The signal at the input of the switching arrangement is switched to a first output of the switching arrangement based on the delayed first square-wave signal at the control input of the switching arrangement. The time span τis matched to the measurement signal such that the switching arrangement is not switched to the first output during the spurious pulse. A signal at the first output is output as an output signal of the circuit.
