置。[Claims for Utility Model Registration] 1. A system comprising a counting means for counting modulation components included in a pilot signal received by a receiver, and an identification means for determining a broadcast mode according to the count value of the counting means. . An audio multiplex broadcast pilot signal identification device configured to cause the operation of the counting means to be executed by a CPU of a frequency synthesizer controller controlling the local oscillation frequency of the receiver. 2. A counting means for counting modulation components included in a pilot signal received by a receiver, and an identification means for determining a broadcast mode according to a count value of the counting means, and a local oscillation frequency of the receiver is provided. An audio multiplex broadcasting pilot signal identification device that executes the operation of the counting means by obtaining a reference signal from a system control oscillator that generates a clock signal to a CPU in a frequency synthesizer controller that controls the frequency synthesizer controller.
