ABSTRACT:
The present invention relates to a device for receiving digital signals including a decoding device for generating p bits from q received signals, p and q being integers such that p is less than or equal to q, one bit of the p bits being generated from an integer number n of received signals, the decoding device including at least one signal processing circuit, the operation of which is clocked by a first clock signal having a frequency which depends on the frequency of reception of the signals received and at least one logic data processing circuit, the operation of which depends on both the receive frequency of the signals received and the number of signals necessary to generate a given bit, including circuitry for generating a second clock signal to clock the operation of the data processing circuit, this circuitry being constructed and arranged so that the second clock signal has a frequency equal to the receive frequency of the received signals and is active or inactive according to the number of received signals required to generate a bit.
