TITLE: IDENTIFYING PROPERTIES OF A SYNCHRONOUS
COUNTER
AIMS
 Expose the student with experience on constructing synchronous counter circuit using
Flip-flop IC, basic gate ICs, breadboard and ETS-5000 Digital kit.
 Promote critical thinking among students by analysing a given circuit and identifying
the behaviour of the digital circuit.
OBJECTIVES
The objectives of the lab activity is to:
 Implement a synchronous counter circuit into physical circuit using Flip-flop IC, basic
gate ICs, breadboard and ETS-5000 Digital kit.
 Completing the next-state table of the counter circuit.
 Sketch the state diagram of the counter circuit.
 Identify the properties of the counter.
PRELIMINARY WORKS
1) Using 7476 IC, connect the synchronous input (J, K) of a JK flip-flop to switches and
its output Q to an LED. Connect the CLK input to a pulsar switch A. Determine the
logic level for each input combinations in table 1 so that result can be realised.
Solution:
