=> Frequency= 5khz , f =1/t = 0.2ms. 7. Determine the output frequency for the circuit given below
A. 28.77 Hz
B. 31.97 Hz
C. 35.52 Hz
D. 39.47 Hz
Answer:A
=> Frequency= 5khz , f =1/t = 0.2ms. 7. Determine the output frequency for the circuit given below
A. 28.77 Hz B. 31.97 Hz C. 35.52 Hz D. 39.47 Hz
Explanation: The output frequency fo = 1/2RC×ln [ (2R1+ R2)/ R2] = 1 / {(2×33kΩ ×0.33µF)×ln[(2×33kΩ +30kΩ)/30kΩ]} = 1/ (0.02175×ln 32) = 39.47 Hz. 8. The value of series resistance in the square wave generator should be 100kΩ or higher in order to
