The Discriminative Frequency Apparatus of Symmetric Scale in TV

WANG Shi-zeng (Department of Physics,Tianshui Normal University, Tianshui Gansu 741001,China)  
This paper instends to introduce the effect of the discriminative frequency apparatus of symmetric scale in TV,the formation of circuit and to discuss how to change the frequency modulation wave of equal amplitude(the second accompanied sound middle-frequency signal of 6.5 MHz)into the frequency modulation wave of regulated amplitude, to detect the frequency modulation wave of regulated amplitude and to obtain the original regulated signal(audio frequency signal).
