Question: Which Of The Following Gates Is Known As Coincidence Detector?

Which is also known as a coincidence detector?

AND logic gates is known as a coincidence detector.

Coincidence means an occurrence of two same things at the same time and a detector which detects it is called a coincidence detector.

It gives high output when both the inputs are high/same or they coincide otherwise it remains low..

What is coincidence logic circuit?

In physics, a coincidence circuit is an electronic device with one output and two (or more) inputs. The output activates only when the circuit receives signals within a time window accepted as at the same time and in parallel at both inputs.

What is the major advantage of ECL logic?

4. A major advantage of ECL logic over TTL and CMOS is ________. C. D….Exercise :: Logic Gates – Filling the Blanks.A.both inputs = 0B.both inputs = 1C.the two inputs are unequalD.both inputs are undefined

What is meant by fan out?

Fan-in refers to the maximum number of input signals that feed the input equations of a logic cell. Fan-out refers to the maximum number of output signals that are fed by the output equations of a logic cell.

Which of the following logic families has the shortest propagation delay?

Which of the following logic families has the shortest propagation delay? Explanation: AS-TTL (Advanced Schottky) has a maximum clock frequency that is 105 MHz. So, the propagation delay will be given by 1/105 sec which is the lowest one. It is followed by S-TTL and HCMOS in terms of increasing propagation delay.

What do NMDA receptors detect?

The CB1 receptors detect the extent of postsynaptic activity through the retrograde release of endocannabinoids, whereas the presynaptic NMDA autoreceptors are sensors for presynaptic spiking.

What is synaptic potentiation?

In neuroscience, long-term potentiation (LTP) is a persistent strengthening of synapses based on recent patterns of activity. These are patterns of synaptic activity that produce a long-lasting increase in signal transmission between two neurons.

What is AMPA receptor?

The AMPA receptor (AMPA-R) is a subtype of the ionotropic glutamate receptor coupled to ion channels that modulate cell excitability by gating the flow of calcium and sodium ions into the cell (Doble, 1995). From: Drug Discovery Approaches for the Treatment of Neurodegenerative Disorders, 2017.

In which of the following gates the output is 1 if and only if at least one input is 1 *?

XOR gate – output is 1 if ONLY one input is 1. NAND gate – output is 1 if AT LEAST one input is 0.

Why is NMDA a coincidence detector?

Only when both Neuron A and Neuron B are activated does the NMDA receptor become activated: magnesium unblocks the channel and glutamate opens the channel. In this way, the NMDA receptor acts as a “coincidence detector” that detects the simultaneous activation of both Neuron A and Neuron B.

What is the output of 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 NOR gates are required to obtain or operation?

To make a NOR gate perform the NAND function, we must invert all inputs to the NOR gate as well as the NOR gate’s output. For a two-input gate, this requires three more NOR gates connected as inverters.

How many and gates are required for a 1 to 8 demultiplexer?

7. How many AND gates are required for a 1-to-8 multiplexer? Explanation: The number of AND gates required will be equal to the number of outputs in a demultiplexer, which are 8. 8.

Which of the following is are the universal logic gates?

The NAND and NOR gates are universal gates. In practice, this is advantageous since NAND and NOR gates are economical and easier to fabricate and are the basic gates used in all IC digital logic families.
