Abstract
A deflection apparatus comprises a deflection amplifier coupled to a deflection waveform modulation circuit such as a diode modulator. A source for generating a modulation signal. The modulation signal comprises an AC component and a DC component, each having levels which define an amplitude ratio. An amplifier alters the amplitude ratio, and the altered amplitude ratio signal is coupled to the deflection waveform modulation circuit for deflection waveform modulation.
