What is AOI and OAI logic?

AND-OR-Invert (AOI) logic and AOI gates are two-level compound (or complex) logic functions constructed from the combination of one or more AND gates followed by a NOR gate. The complement of AOI Logic is OR-AND-Invert (OAI) logic where the OR gates precede a NAND gate.


The OR gate is an electronic circuit that gives a high output (1) if one or more of its inputs are high. The NOT gate is an electronic circuit that produces an inverted version of the input at its output. It is also known as an inverter. If the input variable is A, the inverted output is known as NOT A.

What are switch logic circuits?

Digital logic gates whose inputs and output can switch between two distinct logical values of 0 and 1, can be defined mathematically simply by using Boolean Algebra. But we can also represent the two digital logic states of HIGH or LOW, “1” or “0”, “ON” or “OFF”, as well as TRUE or FALSE.

Which gate is called an inverter?

NOT gate is also known as Inverter because it inverts the given input. For example, if the input is 1 then the output is 0 and vice versa. Thus, the first statement is true.

Is a switch a logic gate?

The switch circuit creates a continuous metallic path for current to flow (in either direction) between its input and its output. The semiconductor logic gate, on the other hand, acts as a high-gain voltage amplifier, which sinks a tiny current at its input and produces a low-impedance voltage at its output.

What is inverted AND gate called?

Inverted AND gate is called NAND gate and Inverted OR gate is called NOR gate.

What is the symbol of inverter?

The Inverter is also called NOT Gate. The Schematic Symbol of a basic Inverter is shown in Figure 1 and Table 1 is its Truth-Table. A Buffer is another Logic Gate that has only one Input, its Output follows the same Logic State as the Input. The Buffer is used as delay element in Digital Electronics.
