Answer:A
Explanation: The output voltage is equal to the RF×C1 times the negative instantaneous rate of change of the input voltage Vin with time. 4. which factor makes the differentiator circuit unstable?
A. Output impedance B. Input voltage C. Noise D. Gain
Explanation: The gain of the differentiator circuit (RF / XC1) increases with increase in frequency at a rate of 20dB/decade. This makes the circuit unstable. 5. The increase in the input frequency of the differentiation amplifier to input impedance creates
