Input voltage = 0, measured after the filter (e.g. accross the 470 nF filter capacitor) Supply rejection of the positive or negative power supply. Vcc ripple =1Vpp, f=100Hz, measured on the sense resistor. Power dissipated in the circuit in the case of the application from Figure 1 and the current in the deflection yoke adjusted to 2.5App. The corresponding power dissipated in the vertical deflection yoke is 2.8W.
