Explanation: The output of the zero crossing detector is differentiated by an RC circuit (RC>>1). So, the voltage at V2 is a series of positive and negative pulses. 13. Mention the application areas of time marker generator can be used
A. Monoshots
B. SCR
C. Sweep voltage of CRT
D. All of the mentioned
Answer:A
Explanation: The output of the zero crossing detector is differentiated by an RC circuit (RC>>1). So, the voltage at V2 is a series of positive and negative pulses. 13. Mention the application areas of time marker generator can be used
A. Monoshots B. SCR C. Sweep voltage of CRT D. All of the mentioned
Explanation: A diode connected at the output of time marker generator circuit converts the sinusoidal signal into a train of positive pulses. So, these pulses are used in triggering the monoshot, SCR, sweep voltage of CRT, etc. 14. Which among the following is used to increase phase angle between different voltages?
