Abstract
The signals transmitted on communication lines in a disturbed environment can be affected by strays. A digital filtering device eliminates these strays by suitable detection of the logic states of the digital signals. The signals received are sampled at a frequency greater than the digital information transmission rate, then detection of a state is effective when a minimum number of samples from among a predetermined number of successive samples is reached. The filtering device restores the rising and descending fronts, and also the high and low states without impairing the information. Application to a highly disturbed electromagnetic environment, notably communication links with circuit breakers.
