The Demorgan’s theorem mostly used in digital programming and for making digital circuit diagrams. There are two DeMorgan’s Theorems. They are described below in detail. According to DeMorgan’s first theorem, a NOR gate is equivalent to a bubbled AND gate. The Boolean expressions for the bubbled AND gate can be expressed by the equation shown below. For NOR gate, the equation is Z = A + B


DeMorgan’s Second Theorem

DeMorgan’s Second Theorem states that the NAND gate is equivalent to a bubbled OR gate.

Z = A . B

Last Answer : SR Flip-Flop   The SR flip-flop, also known as a SR Latch, can be considered as one of the most basic sequential logic circuit possible. This simple flip-flop is basically a one-bit memory ... input is active. This then forms the basis of another sequential device called a D Flip Flop. ...

Last Answer : Full Adder   This type of adder is a little more difficult to implement than a half-adder. The main difference between a half-adder and a full-adder is that the full-adder has three inputs and two outputs. The first two inputs ... : CARRY-OUT = A AND B OR Cin (A XOR B) = A.B + Cin (A ⊕ B) ...
