摘要： A method and apparatus for improving the signal-to-noise ratio of a citizen's band (CB) radio is disclosed. A compander circuit is used in both the transmitting and receiving portions of the citizen's band radio. Demodulated incoming audio signals are expanded by the compander circuit to increase the dynamic range of the incoming audio signals. Outgoing audio signals from a microphone are compressed by the compander circuit to decrease the dynamic range of the outgoing audio signals before they are amplified and transmitted.

摘要： PURPOSE: An apparatus is provided to improve the signal-to-noise radio of a citizen's band (CB), a 10 meter radio receiver and scanner radio receiver. CONSTITUTION: A compander circuit (30) is used in both the transmitting and receiving portions of the radio. Demodulated incoming audio signals are expanded by the compander circuit (30) to increase the dynamic range of incoming audio signals. Outgoing audio signals from a microphone (36) are compressed by the compander circuit (30) to decrease the dynamic range of the outgoing audio signals before they are amplified and transmitted.
