At f=0Hz, φ(f) = – tan-1 (f/fo) = -tan-1(0/5) = 0o 10. At what frequency AOL(f)=A?
A. 50Hz
B. 10Hz
C. 5Hz
D. 0Hz
Answer:A
At f=0Hz, φ(f) = – tan-1 (f/fo) = -tan-1(0/5) = 0o 10. At what frequency AOL(f)=A?
A. 50Hz B. 10Hz C. 5Hz D. 0Hz
Explanation: For any frequency less than break frequency (fo =5Hz) the gain is approximately constant and is equal to A. For example, fo =0Hz,
