    Abstract: PURPOSE:To perform high density recording of sequential chroma signal and separation of an index signal, by multiplexing a sequential chroma signal and index signal with low frequency convertion in time division and recording them with an FM luminance signal. CONSTITUTION:An output signal ST of a color cemera 1 is a synthesis signal consisting of a chroma signal Sc of time division and a pulse width modulation with a luminance signal SYW and an index signal SI for signal separation. The signal ST is applied to a carrier trap circuit 3 and only the signal SYW is picked up and applied to an LPF 4 to form a low frequency luminance signal SY with band limit. After the signal SY is synthesized with a composite synchronizing signal SS at a synthesizer 5, the signal is applied to an FM modulator 7 for FM modulation. On the other hand, the signal ST is picked up for the signal SC including the signal SI at a BPF 11, the picked up signals SI and SC are applied to a separation circuit 12 to separate the both. In low-frequency-converting the signal SC, a carrier CS from the oscillator 20 is phase-shifted at a phase shift circuit 21.

    Abstract: PURPOSE:To obtain the control signals to the correction signals which are used to correct the chrominance signals through a simple constitution by clamping both the integration output of the luminance signal's higher band component and the differential output of the lower band component to the 1st and 2nd potential and then comparing the both clamp output with each other. CONSTITUTION:For composite color video signal SO supplied to terminal 41, only luminance signal Y is extracted after trapping 42 of the carrier chrominance signal and then isolated 43 and sliced 44 to form luminace signal YC. After this, signals YC pass through delay circuit 45 to be compounded 48 via LPF (cut-off frequency: about 350K Hz) 46 and delay circuit 47 to obtain high-band signal YH as well as to obtain clamp output f¦YH¦dt through integrating capacitor C, clamp circuit 52 and others. On the other hand, signal YC is turned to narrow-band signal YLL through LPF (cut-off frequency: about 175K Hz) to obtain clamp output YLL' through differential circuit 54, clamp circuit 57 and others. This clamp output is then applied to comparator 58 along with output f¦YH¦dt. Thus, control signal XB to the correction signal for improvement of the frequency characteristics of the chrominance signal is obtained.

    Abstract: PURPOSE:To make it possible to change over correction signals of a frequency- characteristic improving circuit for color signals smoothly by selectively using a divider circuit bringing switching elements, connected between a current supply and divider circuits, under control. CONSTITUTION:The output terminals of divider circuit M1 for obtaining correction signal XA and divider circuit M2 for correction signal XB are connected in common, and current supply 15 is shared. Switching transistors Qa and Qb, connected between current supply 15 and divider circuits M1 and M2, are controlled to use divider circuits M1 and M2 selectively.

    Abstract: PURPOSE:To detect the phase difference of the desired signal and the unnecessary signal correctly, by detecting the zero cross position of the output of the sampling circuit in which the sampling circuit and the sampling position are variable, and by using the detection signal delayed by 1/4 or 3/4 than it. CONSTITUTION:The output of the sampling circuit 15b sampling the demodulated output in which the sampling circuit 15a and the sampling position are variable, is fed to the zero cross detection circuits 33a and 33b and each zero position is detected. The sampling pulse is respectively produced 36a and 36b at the position delayed by about n/4 or 3n/4 from each zero cross position. The sampling pulses Pd and Pu are added to the output of the circuit 15a and 15b with the gates 27a and 27b, the level is compared and DU ratio is displaying 30, and it is fed to the sampling gate 38a and 38b and the level is compared 40. Thus, the phase difference between the desired signal and unnecessary signal is correctly detected.
