15. Level Stabilization DC Restoration Since the video signal passes through coupling capacitors in the preamplifier stages the DC level information is lost A DC restoration circuit is necessary to maintain a constant black level at the output of the video amplifier for any type of input signal In order to maintain the output stage operating within its linear range the black level is set approximately 10 Yolts below the power supply B In this case the black level 15 preset at 48 Volts DC by adjusting the variable resistor R633 Transistors 0603 and Q604 are part of the DC restoration ete circuitry 5 2 Hith no signal the output of the video amplifier should be a DC level which coincides with the black level of the video Signal and this level depends on the bias point of transistor Q602 Let us consider first a Situation where no signal is applied at the input of the video amplifier and the two extreme conditions expressed under a and b below a If transistor Q603 is OFF the current through R620 R621 is high enough to bias the emitter of 0602 at a high level Since 10602 is an inverting amplifier a nigh level at the input would cause the DC output of the video amplifier to be very close to ground potential b DC transistor Q603 is in saturation its collector voltage would be at ground potential the emitter dis voltage of 0602 at approximately 0 7 Volts and the out lt put of the video amplifier very close to t
