M51326P

Sound (1) measuring the control-pin threshold-voltage value:

Firstly, DC voltage V6 is increased from 3 V to 5 V. Here, we take V

ICL

as the V6 value at which the AC

component in the output waveform from pin 1 is turned off. Then, DC voltage V6 is increased from 7 V to 9 V.

Here, we take V

ICH

as the V6 value at which the AC component in the output waveform from pin 1 is turned on

.

Sound (2) measuring the control-pin threshold-value voltage:

DC voltage V13 is increased from 1 V to 3 V. Here, we take the V13 value at which the AC component in the

output waveform from pin 8 is turned on as V

Measuring the image control pin threshold value voltage:

DC voltage V4 is increased from 1 V to 3 V. This time, we take the V14 value at which the AC component in

the output waveform from pin 12 is turned on as V
