Explanation: In monostable operation mode, if input trigger pulses are generated from a rotating wheel, the circuit will determine the wheel speed whenever it drops below a predetermined value. Therefore, it can be used for speed control and measurement. 7. How can a monostable multivibrator be modified into a linear ramp generator?
A. Connect a constant current source to trigger input
B. Connect a constant current source to trigger output
C. Replace resistor by constant current source
D. Replace capacitor by constant current source
Answer:A
Explanation: In monostable operation mode, if input trigger pulses are generated from a rotating wheel, the circuit will determine the wheel speed whenever it drops below a predetermined value. Therefore, it can be used for speed control and measurement. 7. How can a monostable multivibrator be modified into a linear ramp generator?
A. Connect a constant current source to trigger input B. Connect a constant current source to trigger output C. Replace resistor by constant current source D. Replace capacitor by constant current source
Explanation: The resistor R of the monostable circuit is replaced by a constant current source. So, that the capacitor is charged linearly and generates ramp signal. 8. Determine time period of linear ramp generator using the specifications
