Receiving apparatus

A receiving apparatus comprising:

• a first tuner that performs frequency conversion by multiplying an output signal from an antenna by a first oscillation signal or a signal obtained by applying frequency division to the first oscillation signal;
• a second tuner that performs frequency conversion by multiplying the output signal by a second oscillation signal or a signal obtained by applying frequency division to the second oscillation signal;
• a controller that controls frequencies of the first and second oscillation signals to prevent a frequency of a synthetic signal based on the first and second oscillation signals from falling in frequency bands of channels selected by the first and second tuners;
• and
• a demodulator that demodulates signals resulting from frequency conversion of the output signal from the antenna by the first and second tuners respectively,
• wherein errors of frequencies of the signals resulting from frequency conversion by the first and second tuners under control of the controller from central frequencies of the respective selected channels are smaller than a frequency range which the demodulator is able to demodulate,
• wherein the controller confirms a combination of channels which are selected by the first and second tuners and have a frequency band in which the frequency of the synthetic signal, which is generated based on the first and second oscillation signals, falls;
• and calculates control values for the frequencies of the first and second oscillation signals, and
• wherein absolute values of the control values for the frequencies of the first and second oscillation signals are approximately equal to each other.
