PURPOSE: A broadcast signal receiver is provided to output plural high-frequency broadcast signals which are of different kinds by providing a multi-function circuit for processing a complex base band signal, which is generated from a received high frequency broadcast signal. CONSTITUTION: In a mode A, when a frequency modulation broadcast signal is processed, the complex base band signal is frequency-demodulated, and a multiplex digital audio signal is generated and outputted. In a mode B, the complex base band signal with a corrected frequency, where the digital audio signal or a digital video signal is reproduced, is generated and outputted. In a mode C, when a digital modulation broadcast signal is processed, the complex base band signals with the corrected frequency and amplitude. While the digital audio signal or the digital video signal are generated, when the digital modulated broadcasting signal is processed. Operation is executed in the mode C, the mode C and the mode A and/or the mode B, or the mode A and the mode B by a multi-function circuit(51).
