Experiment 14 - Signal Delay using two Monoflops

In a variety of applications it is necessary to delay a signal for a certain period of time. You can achieve this through a combination of two monoflops.

For this, set up the shown circuit.

Circuit diagram signal delay.

Once you press the pushbutton switch, it takes about half a second until the LED lights up. After another half-second the LED turns off again. The signal is delayed.
