'Active high input' refers to a signal or input condition that is considered "active" or "on" when the voltage level is high, typically close to the supply voltage. This means that when the input receives a high voltage, it triggers a response in the connected circuit or device. Conversely, 'active low input' signifies that the input is active when the voltage is low, usually close to ground level. In this case, a low voltage level triggers the response.

Gate input is LOW-ACTIVE?
A LOW-ACTIVE gate input means that the gate's output is activated or enabled when the input signal is at a low voltage level (typically near 0 volts). In digital logic circuits, this characteristic is often seen in components like NAND and NOR gates. For example, a LOW-ACTIVE NAND gate will produce a high output unless all its inputs are low, while a LOW-ACTIVE NOR gate will produce a high output only when all its inputs are low. This behavior is essential for designing logic circuits that respond to specific input conditions.
What do you mean by strobe gate?
strobe is enable input in a digital IC...if its made active high...it will be enabled..some IC strobe is active low.. Its function is to enable the operation of the IC..or gate or Mux...
Why transistor is called transfer of resistor?
Transistor=Transfer+Resistor. When Transistor operates in active region its input resistance is high and output resistance is low. So,We can consider transistor as a device which transfers its resistance from high to low. And by this property transistor amplifies input signal.
Why most IC are active low?
Most control signals in electronics are active-low signals (usually reset lines, chip select lines and so on). This stems from the fact that most logic families can sink more current than they can source, so fanout and noise immunity increase. (The reason for this is ultimately related to the fact that electrons are negatively charged.) It also allows for wired-OR logic if the logic gates are open-collector/open-drain with a pull-up resistor. Examples of this are the I²C bus and Controller Area Network (CAN).
Does a Digital Voltmeter have a high or low input impedance?
Digital voltmeter has high input impedence.
What is meant by the terms 'active high input' and 'active low input'?
The term "active low" means that the input on an IC requires a logic low for it to be activated, i.e a low voltage (of course the voltage range is dependent on the technology, TTL, CMOS etc) Active high is the opposite... the input requires a logic high for it to be activated. A simple example to illustrate, an 8bit counter can count UP/DOWN this functionality is controlled with only one pin, an active high on that pin to count up or low to count down.
What are the main differences between FETs and BJTs in terms of input impedance?
FET has very high input impedanceBJT has very low input impedance
What is meant by amplifier?
An amplifier amplifies the small input signal to a high signal without changing its freqency.
Gate input is LOW-ACTIVE?
A LOW-ACTIVE gate input means that the gate's output is activated or enabled when the input signal is at a low voltage level (typically near 0 volts). In digital logic circuits, this characteristic is often seen in components like NAND and NOR gates. For example, a LOW-ACTIVE NAND gate will produce a high output unless all its inputs are low, while a LOW-ACTIVE NOR gate will produce a high output only when all its inputs are low. This behavior is essential for designing logic circuits that respond to specific input conditions.
What is the difference between diffusion and active transport?
Diffusion is the movement of molecules from areas of high concentration to areas of low concentration and active transport is the movement of molecules from an area of low concentration to an area of high concentration

Do you need the high input piece for the amp to get it to work?
high input is for speaker level input and low input is rca jacks
Which type of transport is used to move a molecule for a region of low concentration to a region of high concentration?
Active transport is used to move a molecule from a region of low concentration to a region of high concentration. This process requires energy input in the form of ATP to pump the molecule against its concentration gradient.
Why most IC are active low?
Most control signals in electronics are active-low signals (usually reset lines, chip select lines and so on). This stems from the fact that most logic families can sink more current than they can source, so fanout and noise immunity increase.

Does a Digital Voltmeter have a high or low input impedance?

Are diffusion and osmosis active transport?
No, diffusion and osmosis are passive processes where molecules move from an area of high concentration to low concentration without the input of energy. Active transport, on the other hand, requires energy to move molecules against their concentration gradient.
