What type of logical operation is represented by both an input signal and its complemented form?

The logical operation represented by both an input signal and its complemented form is indeed the NOT operation. In the context of digital logic, the NOT operation, or inversion, takes a single input and produces an output that is the opposite (or complement) of that input.

For instance, if the input signal is represented as 'A', the NOT operation would output '¬A' (the complement of 'A'). This means if 'A' is true (or 1), then '¬A' is false (or 0), and vice versa. The essential characteristic of the NOT operation is its unary nature: it requires only one input to produce an output, which directly correlates with having an input and its complemented form.

By contrast, operations like AND, NOR, and XOR require multiple inputs and are defined by how they handle combinations of those inputs rather than an individual input with its negation. This distinction is crucial in understanding how these logical operations behave and are applied in digital circuits and systems.
