In order to retransmit a communication channel at a specific frequency, a receiver (100) may receive a signal including the communication channel's specific frequency. An analog to digital converter (130) may generate a digital signal correlated to the received signal and the digital signal may be passed through a digital filter(140) configured to filter the digital signal and pass frequency components at or around the frequency of the communication channel's specific frequency. A digital to analog converter (150) may generate an analog signal correlated to the filtered digital signal and a transmitter may transmit the analog signal.

Afin de retransmettre un canal de communication à une fréquence spécifique, un récepteur peut recevoir un signal comprenant la fréquence spécifique du canal de communication. Un convertisseur analogique-numérique peut produire un signal numérique mis en corrélation avec le signal reçu et ce signal numérique peut être passé dans un filtre numérique conçu pour filtrer ledit signal numérique et passer des composantes de fréquence à, ou environ à la fréquence associée à la fréquence spécifique du canal de communication. Un convertisseur analogique-numérique peut produire un signal analogique mis en corrélation avec le signal numérique filtré et un émetteur peut transmettre le signal analogique.
