Abstract:
A deflection apparatus, comprising:a deflection winding; a source of a synchronizing input signal at a frequency related to a first deflection frequency; a switching semiconductor responsive to said first input signal and coupled to said deflection winding for generating a deflection current in said deflection winding; a retrace capacitance coupled to said deflection winding to form a retrace resonant circuit with said deflection winding during a retrace interval of a deflection cycle; a source of a modulation input signal at a frequency related to a second deflection frequency; and a modulation amplifier responsive to said modulation input signal for producing, from a current produced in an output stage of said modulation amplifier, a modulation voltage having a frequency related to said second deflection frequency to modulate said deflection current in a manner to provide side raster distortion correction, said modulation amplifier stage including both a current feedback path that increases an output impedance of said output stage and a voltage feedback path that decreases said output impedance.
