Explanation: A conventional ac voltmeter is designed to measure rms value of the pure sine wave whereas, the peak value of the non-sinusoidal wave forms can be a peak detector. 5. State the condition needed to be satisfied by peak detector for proper operation of circuit.
A. CRd ≤ T/10 and CRL ≥ 10T
B. CRd ≤ 10T and CRL ≥ T/10
C. CRd ≥ T/10 and CRL ≤ 10T
D. CRd ≥ 10T and CRL ≤ T/10
Answer:A
Explanation: A conventional ac voltmeter is designed to measure rms value of the pure sine wave whereas, the peak value of the non-sinusoidal wave forms can be a peak detector. 5. State the condition needed to be satisfied by peak detector for proper operation of circuit.
A. CRd ≤ T/10 and CRL ≥ 10T B. CRd ≤ 10T and CRL ≥ T/10 C. CRd ≥ T/10 and CRL ≤ 10T D. CRd ≥ 10T and CRL ≤ T/10
Explanation: For proper operation of the circuit, charging and discharging time constant must satisfy the following: CRd ≤ T/10 and CRL ≥ to 10T. 6. The resistor in the peak detector are used to
