What is the name of the logic gate that has a logic high when all inputs are low?
NAND gate
In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results.
How many outputs can there be in a logic diagram with two inputs?
one output
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.
Can a logic circuit have multiple outputs?
Logic circuits use two different values of a physical quantity, usually voltage, to represent the boolean values true (or 1) and false (or 0). However, a logic circuit can have multiple outputs. There are two basic types of logic circuitry: combinational circuitry and state circuitry.
Is a circuit with only one output but can have multiple inputs?
Best explanation: A logic gate is used to evaluate a Boolean expression. It can have multiple inputs but can have only one output. The different types of logic gates are AND, OR, NOT etc.
When the output of a NOR gate is high?
Detailed Solution. The Output of NOR gate is high when all inputs are low.
How much input and output does a demultiplexer need?
De-multiplexer: De-multiplexer is a device that has a signal inputs line and multiple line outputs. The given figure has one input and two outputs. Hence it is De-multiplexer.
When both inputs are same then the output will be low logic 0 otherwise high logic 1 Identify the logic gate?
XOR gate: the output is 0 if both inputs are same; otherwise, the output is 1. NAND gate: the output is 1 if at lease one input is 0; otherwise, the output is 0.
How do you design a combinational logic circuit?
The design procedure for combinational logic circuits starts with the problem specification and comprises the following steps: Determine required number of inputs and outputs from the specifications. Derive the truth table for each of the outputs based on their relationships to the input.
What is the logic level of an exclusive-OR gate?
Exclusive-OR gates output a “high” (1) logic level if the inputs are at different logic levels, either 0 and 1 or 1 and 0. Conversely, they output a “low” (0) logic level if the inputs are at the same logic levels.
How do you design a circuit with Boolean logic?
Derive the truth table for each of the outputs based on their relationships to the input. Simplify the boolean expression for each output. Use Karnaugh Maps or Boolean algebra. Draw a logic diagram that represents the simplified Boolean expression. Verify the design by analysing or simulating the circuit. Is input greater than or equal to 5?
Why is it important to generate a logic circuit from specification?
Even though CAD tools are used to create combinational logic circuits in practice, it is important that a digital designer should learn how to generate a logic circuit from a specification. Understanding this process allows the designer to better use the CAD tools, and, if need be, to design critical logic sub-circuits by hand.
