摘要
A circuit arrangement for evaluating received oscillations whose maximum possible time duration is predetermined, by determining the time duration of the oscillations. Pulses of a constant frequency are fed to a counter during the time the oscillations are being received and a count representative of the number of counted pulses is stored in a memory as information. Whenever the counter state representing the maximum possible time duration has been exceeded, indicating that the received oscillations are interfering oscillations or noise, the feeding of pulses to the counter is interrupted and the stored information is erased.
