Abstract
A first switching circuit () outputs a first radio signal representing a plurality of time-division multiplexed programs and a second radio signal other than the first radio signal, one at a time according to a switching signal. A voltage control oscillator () outputs a local signal at a frequency suitable for whichever signal outputted. Using the local signal generated, a frequency converter () frequency converts the first and second radio signals to first and second baseband signals, respectively. Via a second switching circuit (), a first baseband unit () and a second baseband unit () are supplied with the first and second baseband signals, respectively, and demodulate them to first and second data signals. A switching unit () supplies the switching signal indicating periods during which the first radio signal represents a user-selected program, to a tuner unit () where the first and second radio signals are processed by time-sharing.
