Abstract
The conventional frequency calibration devices using the color television subcarrier, utilize a frequency synthesizer to generate the calibrated frequency signal into the signal which is the same in nominal frequency with the chroma subcarrier signal. Then it is calibrated by the phase comparison method with the 3.57 MHz chroma subcarrier signal. This paper describes a new method and does not use the frequency synthesizer but uses a simpler device to accomplish the calibration. The measuring accuracy is better than that of conventional devices
