What is a Digital counter? Types of counter in digital circuit
A counter is a sequential circuit, which counts the number of pulses produced by the clock input. The counter is one of the major applications of flip-flops. There are also…
State Diagram and state table with solved problem on state reduction
The synchronous sequential circuits are generally represented by two models. They are Mealy model and Moore model, which we have already discussed in the posts “What is a sequential circuit?”…
What is the excitation table? How it is derived for SR, D, JK and T Flip flops?
The excitation table has the minimum inputs, which will excite or trigger the flip flop to go from its present state to the next state. It is derived from the…
JK flip-flop | Circuit, Truth table and its modifications
JK flip-flop is designed to overcome the invalid or indeterminate state of SR flip-flop. This flip-flop is also a modification of SR flip flop, invented by Jack Kilby, hence the…
What is D flip-flop? Circuit, truth table and operation.
SR flip flop is the basic building block of D flip flop. As you know, SR flip flop has two inputs (S, R) and two outputs(Q and Q’). When you…
SR Flip flop – Circuit, truth table and operation
SR flip flop, also known as SR latch is the basic and simplest type of flip flop. It is a single bit storage element. It has only two logic gates….
What is a flip flop? How it differs from a Latch?
Flip flops and latches are the two important elements of any digital circuit. They are used as a memory device in digital ICs. Both the flip flop and latch are…
What is a sequential circuit? Level Triggering and Edge triggering
In a sequential circuit, the output produced depends not only on the applied input but also on the past history of the outputs. The sequential circuit consists of a combinational…
Code converter | Types | Truth table and logic circuits
The Code converter is used to convert one type of binary code to another. There are different types of binary codes like BCD code, gray code, excess-3 code, etc. Different…
