Digital voltmeter has high input impedence.
An inverter has a high output when the input is low, and a low output when the input is high.
FET s have very high input impedance when compared with Bipolar transistors.
A high signal input to a transistor amplifier gives a high signal output provided it stays linear.
Technically, an OR gate could function with only one input, in which case it would perform the same as if it was not present; when its only input goes high, it would go high, and when the input goes low, it would go low. As a practical matter, the only useful purpose of a single input OR gate would be to have it act as a simple diode, which would be more efficient to simply have a diode in its place.
Flexibility in accessing data
high input is for speaker level input and low input is rca jacks
there is a shift in the supply curve when the cost of input rises.
Digital voltmeter has high input impedence.
it has high input impedance
i was hoping to find the answer here....but i guess NOT -___-
Because op amp consist differential amplifier and they posses high input impedance so that op-amp also posses high input impedance.
An inverter has a high output when the input is low, and a low output when the input is high.
FET s have very high input impedance when compared with Bipolar transistors.
Output impedance in an op-amp is not high - it is low - input impendance is high, and this is because the input stage transistors have high gain.
A circuit (an amplifier) typically has a high input impedance so that it does not unduly load the input circuit. Any such load could cause distortion, and that is generally not desired.
If you have a high input going into the inverter it will have a low output and if you have a low input going into the inverter it will have a high output, the bottom line is it's output is the opposite of the input.
