Abstract

PURPOSE:To establish the constitution stronger in the vibration from external, and excellent in portability and economy, by receiving the TV audio multiplex broadcast signal in which the control signal is selected to a given ratio of integer number with the carrier frequency of the control channel signal, by means of the frequency division circuit. CONSTITUTION:The control channel signal is separated 25 from the signal multiplexed to the TV signal received and made for AM detection 26, so that the control signal selected in the relation of an integer number in fequency with the carrier frequency of control channel signal can be obained. Further, the frequency of the control signal obtained with detection 26 and the frequency of the signal obtained from the control channel signal with frequency division 27,28, are compared 29, 30, and the audio multiplex broadcast of the format represented by the control signal when the both frequencies are in agreement is received. Thus, the receiver is stronger against external vibration, excellent in the portability and economy.
