Introduction
•
When logic gates are connected together to produce a specified output for
certain specified combinations of input variables, with no storage involved, the
resulting circuit is called combinational
logic circuit. In combinational logic circuit, the output variables are at
all times dependent on the combination of input variables.
•
A combinational circuit consists of input variables, logic gates, and output
variables. The logic gates accept signals from the input variables and generate
output signals. This process transforms binary information from the given input
data to the required output data. Fig. 4.1.1 shows the block diagram of a
combinational circuit. As shown in Fig. 4.1.1, the combinational circuit
accepts n–input binary variables and generates output variables depending on
the logical combination of gates.
