Explanation: The value of internal resistor and capacitor and feedback resistor and capacitor of the differentiator values should be selected such that fa < fb < fc to make the circuit more stable. 9. Which application use differentiator circuit?
A. None of the mentioned
B. FM modulators
C. Wave generators
D. Frequency Shift keying
Answer:A
Explanation: The value of internal resistor and capacitor and feedback resistor and capacitor of the differentiator values should be selected such that fa < fb < fc to make the circuit more stable. 9. Which application use differentiator circuit?
A. None of the mentioned B. FM modulators C. Wave generators D. Frequency Shift keying
Explanation: The differentiators are used in FM modulator as a rate of change detector. 10. A sine wave of 1vpeak at 1000Hz is applied to a differentiator with the following specification: RF =1kΩ and C1=0.33µF, find the output waveform?
