In ROM each bit combination of the input variables is called .....

in ROM each bit combination that comes out of the output lines is called

A sequential circuit consits of logic gates whose outputs at anytime are determined directly from the present combination of inputs without regard to previous inputs

.... circuit employ memory elements (binary cells)

In many applications, the souce and/or destination are storage registers

for n input variables there are ... possible combinations of binary input values

an input variable may appear in two wires supplying both the nomal and complement forms to the circuit's input

The design of combinational circuits starts from the verbal outline of the problem. It ends in a logic circuit diagram or a set of boolean functions

The boolean output functions from the truth table are simplified by any available method, such as algebric manipulation, tha map method, or the tabulation procedure

the combinational circuit that performs the addition of 3 bits

number of inputs and outputs of half adders are

number of inputs and outputs of a full adder are

Express the Boolean function
F = xy + x`z
in a product of maxterm form

The exclusive-OR, we can express it as .......

................. represents EOR gate

................. represents AND gate

.................... represents equivalence gate.
