What is the output if a NOR gate with one high input AND one low input?

What is the output if a NOR gate with one high input AND one low input?

Unsourced material may be challenged and removed. The NOR gate is a digital logic gate that implements logical NOR – it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results.

Can a logic gate have 1 input?

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 inhibit input in logic gates?

It is basically an AND gate which has one of its inputs negated by an inverter. The input which is negated acts to inhibit the gate. Or we can say the gate will behave like an AND gate only when the negated input is set at a logic level ‘0’. Now we will look at the truth table of the above drawn gate.

When one of the input to the AND gate is at logic zero level the out put will be?

When either input is a logic 1, the output will be 0. The only combination of inputs that results in an output of 1 is A = 0 and B = 0. The two-input NOR gate can be implemented in CMOS as shown in Fig.

When one of the input to the AND gate is at logic zero level the output will be?

A logical inverter, sometimes called a NOT gate to differentiate it from other types of electronic inverter devices, has only one input. It reverses the logic state. If the input is 1, then the output is 0. If the input is 0, then the output is 1.

What is the output of an AND gate if the inputs are 1 and 0?

The output of the circuit will be the opposite of the input. If 0 is input, then the output is 1. If 1 is input, then 0 is output. The Boolean expression is written as Q = NOT A.

Which of the following operations produce a 1 if the input bits are 1 AND 1?

Explanation: An OR gate gives the result as 1 if any one of the inputs is one. Its expression is A+B.

What is inhibitor circuit?

The Inhibit™ function is defined as a circuit that will electronically. extinguish the output of a DC Drive by closing a set of contacts. The Inhibit™ acts as. an electronic switch since the full output of a DC Drive (which can be as high as 16.

What is enable input in Gates?

The enable input of an OR gate is low active. This means that the output will be a copy of the input signal when the enable is low. When the enable input of an OR gate is high, the output of the gate will be a constant high signal.

When do logic gates imply a valid output?

It’s sometimes important to recognize two distinct kinds of “AND” gates, and likewise with “OR”, “NAND”, “NOR”, etc. Those where a valid high on all inputs will guarantee a valid high output, and where a valid low signal at any input will imply that the output will be low, whether or not other inputs are at valid logic levels.

What happens when one input is undefined in a circuit?

If the circuit is drawn with the latter style of gates, is behavior will likely be much less certain. It would in practice probably stabilize after awhile to A=1 B=0, but that’s hardly guaranteed. It is undefined “within the constraints that each output or input can only be 0 or 1”.

What happens when the and GATE input is low?

When the AND gate enable input is low, the output will remain a constant low signal. A two input OR gate can also be used with one input the desired signal and the other input is the enable. The enable input of an OR gate is low active. This means that the output will be a copy of the input signal when the enable is low.

Can a NOR gate be used to output a 1?

This can be implemented with an AND gate with one inverted input, or with a NOR gate with one inverted input. Devices that implement this logic are the (SN)74xx1G58, (SN)74xx1G97, and (SN)74xx1G98. CL. CL. You could simply use a buffer chip with an active low enable. Something like an SN74LV1T125 might work. Hook A to A, B to OE, Y is your output.
