Inventor: MIYAZAKI SHINICHIRO
IPC: H04N5/95
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To eliminate jitter on a horizontal synchronizing signal in a composite video signal. SOLUTION: A phase comparator circuit 82 compares a phase of a horizontal synchronizing signal (input signal) with a phase of a pulse with the same period as the horizontal synchronizing signal generated by a timing generating circuit 81 and a discrimination circuit 83 discriminates whether or not the period of the horizontal synchronizing signal is stable based on the comparison result. A switch 84 selects a terminal 84a or 84b based on the discrimination result and either of the pulse generated by the timing generating circuit 81 or the horizontal synchronizing signal is outputted thereby. Then the timing generating circuit 81 controls a phase of the pulse generated by itself corresponding to the signal outputted from the switch 84.

Title: Frequency conversion circuit
Inventor: ATSUTA HIROSADA
IPC: H04B1/04
Filed: 1992-09-10
Abstract: PURPOSE:To eliminate the leaked local oscillation signal for a frequency conversion circuit which sends the intermediate frequency modulated wave obtained by a base band signal after converting the intermediate frequency into the radio frequency by synthesizing the branched local oscillation signal and the leaked local oscillation signal with the same amplitude and the reverse phase. CONSTITUTION:A local oscillation signal is branched and the phase of this signal is controlled by a phase shifter 7 so that the leaked local oscillation signal is eliminated. Then the amplitude of the local oscillation signal is controlled by an attenuator 8. The phase and the amplitude of the local oscillation signal are set equal and reverse to those of the leaked local oscillation signal. Then the synthesization of electric power is carried out by a power synthesizer 9. At the same time, the phase shift extent of the shifter 7 and the attenuated variable of the attenuator 8 are always controlled by the external control signal. Thus the fluctuation of the leaked local oscillation signal can be satisfactorily suppressed.
