Variation in the operating frequency of op-amp causes
A. Variation in gain amplifier
B. Variation in gain phase angle
C. Variation in gain amplitude and its phase angle
D. None of the mentioned.
Answer:A
Variation in the operating frequency of op-amp causes
A. Variation in gain amplifier B. Variation in gain phase angle C. Variation in gain amplitude and its phase angle D. None of the mentioned.
Explanation: The gain of the op-amp is a function of frequency. It will have a specific magnitude as well as a phase angle. 2. A graph of the magnitude of the gain versus frequency is called
