What else can I help you with?
Why emitter follower preferred to transforms as a impedance matching?
because it has high input impedance and low output impedance
Definition of low impedance medium impedance and high impedance?
For instance: A microphone rated at 150 ohms to 300 ohms is considered low impedance. About 600 to 2 000 ohms is medium impedance, and 10 000 ohms or more is high impedance.
Compared to bipolars FETs have-a high input impedance b low input impedance c same input impedance?
FET s have very high input impedance when compared with Bipolar transistors.
Is 5000 ohm is high impedance?
Relative to 500 ohms 5000 ohms is a high impedance. It is ten times higher.
Which is better high input impedance or low input impedance and why?
That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
In a multistage amplifier input impedance is high and output impedance is low justify the statement?
no. input impedance is low & output impedance is high
Why emitter follower preferred to transforms as a impedance matching?
because it has high input impedance and low output impedance
What is the difference between high impedance and low impedance?
The difference between high impedance and low impedance is the amount of resistance in an electrical circuit. High impedance means there is a high level of resistance, which limits the flow of current. Low impedance means there is a low level of resistance, allowing for a greater flow of current.

When does ALE float to its high-impedance state?
These pins are not at their high-impedance stateduring a hold acknowledge.

FET s have very high input impedance when compared with Bipolar transistors.
Definition of low impedancemedium impedance and high impedance?
There is no precise definition, but for instance: A microphone rated at 150 ohms to 300 ohms is considered low impedance. About 600 to 2 000 ohms is medium impedance, and 10 000 ohms or more is high impedance.
What are the advantages of using a low impedance microphone compared to a high impedance microphone?
A low impedance microphone has better signal quality, less interference, and can transmit audio over longer distances compared to a high impedance microphone.
What are the dc characteristics of an OP-AMP IC 741?
High gain high input impedance low output impedance
Is 5000 ohm is high impedance?

What is impedance phlebography?
Impedance phlebography is a noninvasive test that uses electrical monitoring to measure blood flow in veins of the leg.
