Abstract: PURPOSE:To prevent white inverting phenomenon by providing a flat frequency in prescribed band width, in which the carrier frequency of an FM modulated luminance signal is obtained as the center, in an equalizer circuit at the digital demodulator provided with the equalizer circuit to decide the frequency characteristic corresponding to the level of the FM modulated luminance signal. CONSTITUTION:The difference of this device from the conventional one is that four serially connected delay circuits are provided at the input side of delay circuits 51 and 53 and the output side of delay circuits 52 and 54. Namely, the two steps of a cosine equalizer circuit is provided corresponding to conventional one step of a cosine equalizer circuit. Thus, when a transmission function is defined as H(Z), for this H(Z), the condition of H(Z)=1/8K-KZ<-4>+Z<-6>+1/8 KZ<-10> is established, the frequency characteristic is shown by (a) in the figure, a sum frequency signal is not erroneously recognized as any luminance signal in an equalizer circuit 5, and the white inverting phenomenon is not generated. Further, (fY+2fC) is defined as the object as shown by (b) in the figure, for example, it is enough only to set the band width larger than 4fC.

Abstract: PURPOSE:To prevent the read pulse applied to the secondary side of a pulse transformer from being affected on the primary side, by providing a constant voltage diode for an emitter of a transistor (Tr) short-circuiting the primary side of a pulse transformer. CONSTITUTION:When a switch 7 is closed, a Tr turns on and short-circuits the primary side 13a of a pulse transformer 13. In this case, when a read pulse RD is applied, since an impedance viewed from the secondary side 13b of the pulse transformer 13 is small, a flip-flop 11 is set to a low level. With the switch 7 opened and the Tr in off-state, when the pulse RD is applied, a voltage induced at the primary side of the pulse transformer 13 is cut with a constant voltage diode Z and no base current flows to the Tr. Then, flip-flop 11 can read high level without error.
