What does the 0 and 1 represent in logic gate?

A logic gate is a device that acts as a building block for digital circuits. Most logic gates have two inputs and one output. Logic gates are based on Boolean algebra. At any given moment, every terminal is in one of the two binary conditions, false or true. False represents 0, and true represents 1.

What is meant by logic levels?

A logic level is one of several states that a digital signal can possess, expressed as a DC (direct-current) voltage with respect to electrical ground. Usually, the term refers to binary logic in which two levels, or states, can exist: logic 1 (also called the high state) and logic 0 (also called the low state).

Which gate produces a 1 only if all its inputs are 1 and a 0 otherwise?

OR gate
B. False

1.	Logic diagrams and truth tables are equally powerful in expressing the processing of gates and circuits. A
6.	The output value of an OR gate when both inputs are 1 is 1. A
7.	The output of an OR gate when one input is 0 and one input is 1 is 0. B
8.	The output value of an XOR gate is 0 unless both inputs are 1. B

What are some common voltages for logic 1s and 0s?

“Acceptable” input signal voltages range from 0 volts to 0.8 volts for a “low” logic state, and 2 volts to 5 volts for a “high” logic state.

What is difference between CMOS and TTL?

CMOS stands for Complimentary Metal-oxide Semicodictor while in TTL stand for Transistor-Transistor Logic. CMOS circuit uses a field-effect transistor by connecting NMOS and PMOS, the TTL circuit uses bipolar junction transistor. The design of the CMOS can be considered to be very simpler as compared to the TTL.

What is meant by logic 0?

“Logic 0” and “logic 1” represent binary digits (0 and 1) or Boolean logic conditions (true and false). Thinking in terms of logic 0 and logic 1 allow engineers to design circuits and logic gates at a high level of abstraction that is removed from implementation considerations.

Which logic gate produces an output of 1 only if both its inputs are 0 OR both inputs are 1?

Combinational circuits are built of five basic logic gates: AND gate – output is 1 if BOTH inputs are 1. OR gate – output is 1 if AT LEAST one input is 1. XOR gate – output is 1 if ONLY one input is 1.

What is the difference between logic gate AND logic circuit?

Logic circuits are also called logic networks, are structures which are built up from certain elementary circuits called logic gates. Each logic circuit may be viewed as a machine L which contains one or more input devices and exactly one output device.

What is the difference between logic 1 and logic 0?

Usually, the term refers to binary logic in which two levels, or states, can exist: logic 1 (also called the high state) and logic 0 (also called the low state). In most circuits, logic 1 is represented by approximately +5 V (positive 5 volts) relative to ground, while logic 0 is represented by approximately the same voltage as ground (0 V).

What is the difference between logic 0 and 1 on RS232?

On an RS232 line, Logic 0 is +10V, and logic 1 is -10V. On a differential line like a USB, logic 0 is the white wire is 3.5V higher than the green wire – for a logic ‘1’, the green wire is 3.5V higher than the white.

What is a logic level?
