  • Diversity receiver with improved sensitivity
    Patent number: 5819167
    Abstract: A radio receiving apparatus has a main receiver (10) and a diversity receiver (12). The main and the diversity receivers are linked by a mute logic (34) which is capable of applying a mute signal to either receiver in order to reduce the sensitivity of that receiver. Receiver sensitivity is reduced in order to prevent a comparatively strong received signal causing ringing (persistence of vibration) in the receiver filter.
