The term Product-of-sum in Boolean algebra means
The Product of Sum (POS) expression comes from the fact that two or more sums (OR's) are added (AND'ed) together. That is the outputs from two or more OR gates are connected to the input of an AND gate so that they are effectively AND'ed together to create the final (OR AND) output.
Which expression is computed by the following NAND-gate circuit diagram:
What is the Boolean expression for the following circuit:
A multiplexer is also known as
In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line.
The quantity 837 in excess-3 BCD code would be represented as
The quantity 837 is first converted to BCD representation then it is incremented by 3 bit by bit.
Half-adder is also known as
A half adder is also known as XOR gate because XOR is applied to both inputs to produce sum.
A comparison between serial and parallel adder reveals that serial order
Comparison between serial and parallel adder reveals that serial adder is serial adder is a sequential circuit. A parallel adder is a combinational circuit. In serial adder, propagation delay is less. In parallel adder, propagation delay is present from input carry to output carry.
How many full adders are needed to construct an m-bit parallel adder ;
We can construct a m-bit parallel adder by,
(i) m-full adders OR
(ii) (m - 1) full adders and one half adder OR
iii) (2m - 1 ) full adders and (n - 1) OR GATES
