S-R Flip-Flop

S-R Flip Flop It is basically S-R latch using NAND gates with an additional enable input. It is also called as level triggered SR-FF. For this circuit in output...

Flip-Flops

Flip Flop Flip flop is a sequential circuit which generally samples its inputs and changes its outputs only at particular instants of time and not continuously. Flip flop is...

Introduction to Combinational circuits

Combinational circuit is circuit in which we combine the different gates in the circuit for example encoder, decoder, multiplexer and demultiplexer. Some of the characteristics of combinational circuits are...

Boolean Laws

Boolean Laws There are six types of Boolean Laws. Commutative law Any binary operation which satisfies the following expression is referred to as commutative operation Commutative law states that...
