<p>For a broadcasting system using mutually adjacent frequency bands for analog broadcasting and digital broadcasting, a receiver is provided which comprises an analog processing circuit for producing audio signals by processing received analog broadcasting signals, a digital processing circuit for producing audio signals by processing received digital broadcasting signals, a switch circuit for selectively receiving audio signals from the analog processing circuit and audio signals from the digital processing circuit, a control circuit that controls the voltage for driving the digital processing circuit, and a detector circuit that detects a tuned digital broadcasting station. Since the control circuit applies the driving voltage to the digital processing circuit only when the detector circuit detects a digital broadcast being tuned, thus reducing power consumption.</p> |
