Question No. 02                                                                                                                         Marks 10

Suppose the light signs of a shop are continuously blinking after every 2 seconds. You have been given information that input pulse provided to the lighting circuitry is clocking at a rate of 4 Hz.

Now, your task is to identify the number of J-K flip flops used to make your circuit blink every 2 seconds and draw the timing diagram of this circuit for every output like F0, F1 etc.

BEST OF LUCK
