CS201 Lab: Sequential Design

Objectives of this lab:


	To investigate flip-flop characteristics. 
	To verify sequential design procedures by building a simple counter.

Preparation


	Read lab lecture notes which contains the Sequential Design Procedure.

Lab Assignments

  1. Implement the following circuit to test the characteristics of a D flip flop.

  2. Experimentally verify the JK flip-flop state table with the following circuit.
    Is the JK flip-flop positive or negative edge triggered?________
    Verify the excitation table.
