Which of the following statements is true about NOT logic?

The correct answer is that all of the statements provided are true regarding NOT logic and its associated concepts.

In digital logic design, NOT logic, also known as inversion or negation, plays a fundamental role. It takes a single input and produces the opposite output. This means that if the input is true (1), the output will be false (0) and vice versa.

The statement about NOR logic being formed by two or more normally closed (N.C.) switches in series accurately describes how NOR gates operate. When all N.C. switches are closed, the output is low (false). It is only when at least one switch opens that the output becomes high (true), fulfilling the behavior of a NOR operation.

Similarly, the statement that NAND logic is created by series-connected normally open (N.O.) switches aligns with the functionality of NAND gates. In this configuration, the output is low only when all switches are closed, leading to a high output if at least one switch is open, hence demonstrating the aspect of NAND logic.

The assertion that NOT logic does not apply in binary circuits is incorrect because NOT logic is a crucial part of binary circuits, functioning to invert binary signals which can be essential for various logic operations within those systems.

By recognizing that
