Frequency response of µA709C for various closed loop gain is shown. Choose the curve that has wider bandwidth and high gain?
A. Curve 4
B. Curve 3
C. Curve 2
D. Curve 1
Answer:A
Frequency response of µA709C for various closed loop gain is shown. Choose the curve that has wider bandwidth and high gain?
A. Curve 4 B. Curve 3 C. Curve 2 D. Curve 1
Explanation: To get a high gain and relatively wider bandwidth, the compensating components for curve 1 should be used. Curve 1 has the gain equal to 60dB and bandwidth nearly equivalent to 10MHz. 4. When does a system said to be stable?
