Objective:

The objective of this assignment is to prepare students to familiar with concepts of latches, flip flops and their applications. Furthermore it will enhance one’s ability to differentiate the operations of different types of flip flops.

Question No: 1

For the positive Edge- Triggered J-K flip flop with preset and clear inputs as shown in figure (a) below. Determine the Q outputs for the inputs shown in timing diagram (b) if Q is initially low.                                                                                 Marks 10
