Horizontal deflection circuit with timing correction

A deflection circuit for generating deflection current in synchronization with synchronizing signals, comprising:

• a deflection winding;
• output deflection means coupled to said deflection winding and responsive to driving signals for generating said deflection current in said deflection winding during each deflection cycle, including means for generating retrace signals indicative of the initiation of the retrace interval in said deflection cycle;
• oscillator and driver means coupled to said output deflection means and responsive to control and correction signals for generating said driving signals at predetermined instants in said deflection cycle;
• synchronization means coupled to said oscillator and driver means and responsive to said synchronizing signals and said retrace signals for providing said control signals to said oscillator and driver means for synchronizing said deflection current with said synchronizing signals;
• and
• correction means coupled to said oscillator and driver means for providing said correction signals to said oscillator and driver means for correcting for variations in initiation of said retrace interval that are not adjusted by said synchronizing means, said correction means comprising:
• sawtooth generating means responsive to said retrace signals for providing a sawtooth voltage;
• a peak separator coupled to said sawtooth means for providing voltage pulses during a peak voltage excursion of said sawtooth voltage;
• and
• means for coupling said voltage pulses to said oscillator and driver means for providing said correction signals.
