Page 31: Circuit Description
Introduction In stereo sets, the signal goes via the SAW filter (position 1002/ The 'L01.1L AC' chassis is a global TV chassis for the model 1003), to the audio demodulator part of the UOC IC 7200. The year 2003 and is used for TV sets with screen sizes from 20" to audio output on pin 33 goes to the stereo decoder 7831/ 7861. - Page 32 EN 72 L01.1L AC Circuit Description Video Signal Processing Once the signal source is selected, a chroma filter calibration is performed. The received color burst sub-carrier frequency is 9.3.1 Introduction used for this. Correspondingly, the chroma band pass filter for...

During the first half of the slope, the spot is delayed and the slope becomes steeper.

Active/ inactive Over Power Protection During the primary stroke, the rectified AC input voltage is measured by sensing the current drawn from pin 4 (DEM).
