Abstract
An analog/digital receiver comprises a noise detecting circuit for checking whether a noise component, output from an analog signal detecting means, is not less than a specified value, and an RSSI detecting circuit for checking whether received signal strength, output from the receiver, is not less than a specified value. A discriminating circuit is included for making a determination as to whether the received input is an analog modulation signal or a digital modulation signal according to the result of the determination made by the noise detecting circuit as well as by the RSSI detecting circuit. A select switch selects the output from either the digital signal detecting circuit or the analog signal detecting circuit.
