Question

2. Work out three tables for the circuit and the various inputs described below. In each case, start with all the flip-flops off. a.IfD is always high, indicate what happens after each of the first 10 clock b.IfD is high only for the first clock pulse, indicate what happens after cach c. IfD is high for the 1st, 3rd, and 7th clock pulses, indicate what happens d.Do you recognize this circuit? What is its name? pulses. of the first 10 clock pulses. after each of the first 10 clock pulses. J Q J Q J 0 Clock

Explanation / Answer

a) If D is always high the input will always be 1 to first flip flop. The values will propogate at every clock pulse.

b) If D is high only for the first clock pulse and 0 for the rest.

c) If D is high for 1st , 3rd and 7th clock pulse.

d) The circuit above is a serial in serial out shift register using JK flip flop. The J K flip flop is used as D flip flop.

Clock pulse A B C D E - 0 0 0 0 0 1st 1 0 0 0 0 2nd 1 1 0 0 0 3rd 1 1 1 0 0 4th 1 1 1 1 0 5th 1 1 1 1 1 6th 1 1 1 1 1 7th 1 1 1 1 1 8th 1 1 1 1 1 9th 1 1 1 1 1 10th 1 1 1 1 1
