Title: Frequency modulator
Inventor: KUDOU HIROSHI
IPC: H04N9/64
Filed: 1983-05-27
Abstract: PURPOSE:To obtain a frequency modulator having stable frequency by using a reference frequency inputted at no signal period in a vertical video image blanking at each frame. CONSTITUTION:An output of a voltage controlled variable frequency oscillator 3 is inputted to a phase comparator 4. On the other hand, a reference frequency fref inputted at no signal period in the vertical video image blanking at each frame is inputted to a comparator circuit 4 by a sampling switch 6 switched by a sampling pulse SP. As a result of comparison, a frequency voltage Vref is held in a voltage addition holding circuit 2. Further, a frequency shift voltage controlled by a line switching pulse LS and a signal voltage are superimposed on the reference voltage Vref at the video image period and the result is inputted to the oscillator 3. As a result, the signal is frequency-moduated by taking the stabilized frequency as a center. Thus the frequency modulator having stable frequency is obtained.
