Class Information
Number: 315/371
Name: Electric lamp and discharge devices: systems > Cathode ray tube circuits > Cathode-ray deflections circuits > With ray deflection distortion correction or reduction > By modulation of deflection waveform
Description: Subject matter wherein the electrical circuit includes a source of a deflection waveform which is delivered to the deflection means and the electrical network delivers another waveform or signal to the electrical circuit or the deflection means to modulate the deflection waveform so that a composite waveform is delivered to the deflection means to correct or diminish some type of distortion received by the energized electrical circuit, deflection means, or the cathode-ray tube.
