INPUT SIGNAL
VIF/SIF
Note 1: The timing and pulse width of the horizontal blanking pulse should be as shown in the following figure by adjusting the variable
The variable resistor at pin 15 of the TTL IC, M74LS221P, is used to fix the timing at 8 s and that at pin 7 is used to fix the pulse width at
12 s.
