Abstract
A radio selective call receiver includes an instruction input device which produces an analog input signal and a radio receiver which receives a radio signal and demodulating it to produce an analog demodulated signal whose amplitude varies in a symbol period. A selector selects one of the analog input signal and the analog demodulated signal and is connected to an A-D converter. The A-D converter is shared between the analog demodulated signal and the analog input signal. An A-D conversion of the analog demodulated signal is performed at intervals synchronizing with the analog demodulated signal. An A-D conversion of the analog input signal is performed within a time period during which the analog-to-digital conversion of the analog demodulated signal is not performed.
