Abstract

Herein disclosed is a broadcast wave receiving apparatus, comprising: first and second tuning circuits each having a resonance frequency; first controlling means for controlling one of the first and second tuning circuits to ensure that the resonance frequency of one of the first and second tuning circuits is tuned to a specific frequency before allowing one of the first and second tuning circuits to detect a broadcast wave at the specific frequency; judging means for judging whether or not to receive the broadcast wave detected by one of the first and second tuning circuits on the basis of predetermined threshold information on the broadcast waves; and second controlling means for controlling the other of the first and second tuning circuits to ensure that the resonance frequency of the other of the first and second tuning circuits is tuned to the specific frequency before allowing the other of the first and second tuning circuits to produce a broadcast signal indicative of the broadcast wave detected by one of the first and second tuning circuits in response to the judgment of the judging means.
