<p>PROBLEM TO BE SOLVED: To provide an audio broadcasting receiver capable of calculating a time difference between reception output of a program of digital audio broadcasting and reception output of a program of analog audio broadcasting with a little number of times of arithmetic operation.SOLUTION: In the audio broadcasting receiver, a control section 6 calculates a time difference from an output signal from a first receiving section 1 and an output signal from a second receiving section 2 and when selecting and switching a signal to be outputted by switching means 5 in accordance with receiving states of the first receiving section 1 and the second receiving section 2, a delay amount of delay means is controlled in accordance with the time difference. In the audio broadcasting receiver, the control section 6 performs arithmetic operation to determine a correlation between the output signal of the first receiving section 1 and the output signal of the second receiving section 2, calculates the time difference between the output signal of the first receiving section 1 and the output signal of the second receiving section 2, and changes the number of times of arithmetic operation for determining the correlation, in accordance with the number of times of determining the correlation up to the moment.</p> |
