Abstract
In radio communication systems transmitting voice and data, data is frequently transmitted at the beginning of the transmission, and this may then be followed by voice. The sound of the data in the receiver loudspeaker is unnecessary and often annoying. This sound is eliminated by a muting circuit which initially mutes the receiver for a predetermined time following receipt of a carrier signal, and then mutes the receiver when data is detected. After the data ends, the receiver is unmuted if a carrier is still present.
