Combination of Logic Circuits                                 Combination circuits are a basic collection of logic gates. Their outputs depend only on the current inputs. Combination circuits are also time-independent. Along with the absence of concepts like past inputs, combination circuits also do not require any clocks. The result of these properties is a simple circuit capable of implementing complex logic using only logic gates. An easy to understand example is a full adder.     Block diagram of a combination logic circuit :   combinational logic circuit block diagram   What are the different types of combinational logic circuits? There are three main types of combinational logic circuits.          1) Arithmetic and logical combinational circuits – Adders, Subtractors, Multipliers, Comparators.         2) Data handling com...
