My apologies for creating such a big confusion....... my design question has been modified
I now have to design a circuit which provides a train of pulses of width ranging from 0.1ms to 1s of duty cycle that can be varied from 25% to 75%
As suggested i have decided to go with the...
WE neednt vary duty cycle continuously....a provision to adjust duty cycle along and separate provision to addjust time period is required....i js got that clarified from my prof!!
PROBLEM STATEMENT
Without using a microcontroller or a dedicated timer IC, implement a circuit which, when a trigger is applied , will provide a +ve pulse of amplitude 3V, whose width can be varied from 0.1ms to 10s. You may not use any capacitor greater than 1uF or resistor larger than...
