Title: Time base corrector
Inventor: NISHIHARA MICHIHARU
IPC: H04N5/953
Filed: 1987-08-31
Abstract: PURPOSE:To reduce an electrical quantity of correction and to realize practical time base correction with high performance, by correcting a low-pass jitter component by a mechanical time base correction means, and correcting a high- pass jitter component by an electronic time base correction means. CONSTITUTION:A time base error detection circuit 9 performs the time base correction by outputting only a high-pass error component out of detected time base error components to a variable delay line 7 as the control signal of the variable delay line 7. Therefore, no time base error signal is outputted from the time base error detection circuit 9 to a driving circuit 10, and no time base correction by a time base coil 12 is performed. In other words, the primary object in mechanical time base correction by an arm stretcher lies in the correction of the basic component (low-pass component) of jitter, which makes worse responsiveness by reducing a servo system gain smaller than ever. On the other hand, since the primary object in electronic time base correction using the variable delay line 7 lies in the correction of a high-pass jitter component, the electrical quantity of correction can be reduced. In such a way, it is possible to realize the time base correction in which a mechanical and an electronic systems are used jointly together.
