Circuit and method of linearity correction for CRT deflection circuits |
摘要 |
Electronic apparatus and method is disclosed for generating a linearity correction signal for use in or with a CRT electron beam deflection circuit. In a preferred embodiment, transistor is used to vary the parameters of a multiple feedback infinite gain bandpass filter such that the filter is essentially on the point of oscillation during trace, but is highly damped during retrace.
