Question

Series connection of IC timers can produce an output consisting of a delayed pulse of fixed duration. The first timer fixes the delay with its negative transition triggering the second timer. The second timer sets the duration of the output pulse. The two timers are capacitive coupled with a pull-up resistor on the input of the second timer: the RC time constant of this coupling circuit must typically be less than 50 mu s for a 555 timer. Design a two IC timer circuit that will produce an output pulse that is delayed from an input triggering pulse. The design specifications are: Input trigger 5V to 0V for 8 mu s Output delay 2 ms plusminus 6 mu s (from beginning of trigger) Output pulse duration 06 ms plusminus 10 mu s Verify your design with Multisim simulation
