What is a NOT gate (also known as an INVERTER)?
B
Answer
Circuit design and power supplies
Type
A
A circuit that produces a logic "1" at its output when the input is logic "1"
B
A circuit that produces a logic "0" at its output when the input is logic "1"
C
A circuit that does not allow data transmission when its input is high
D
A circuit that allows data transmission only when its input is high
Answer Notes
A NOT gate, frequently called an inverter, is the simplest type of digital logic gate. It only has one input and one output, and its sole function is to reverse the logic state.
If you feed it a logic "1" (high), it outputs a logic "0" (low). Conversely, if you feed it a logic "0", it outputs a logic "1". It essentially flips the bit to its opposite state.
Distractors that mention allowing or blocking data transmission are describing a gate or buffer switch, not a basic inverter. An inverter always passes the signal but simply reverses its logical polarity.
