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
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.
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.
Does a Digital Voltmeter have a high or low input impedance?
Digital voltmeter has high input impedence.
What is the Difference between low and high impedance relays?
It depends on the resistance level in that area if the soil have low resistance then they will use high impedance system and vice versa..so reason behind this have to reduce fault current.
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.
Are drum triggers high or low impedance?
V-Drums, for instance, have an output of 330 ohms, making them low- medium-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
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.
Why emitter follower preferred to transforms as a impedance matching?
because it has high input impedance and low output 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
What are the differences between low impedance and high impedance, and how do they affect the performance of electronic devices?
Impedance refers to the opposition of a circuit to the flow of alternating current. Low impedance means there is less opposition, allowing more current to flow easily. High impedance means there is more opposition, limiting the flow of current. In electronic devices, low impedance can lead to better performance and efficiency, while high impedance can cause signal loss, distortion, and reduced overall performance.

What is the definition of low earth orbit?
An earth orbit that is lower to earth then both a medium and high earth orbit.
What type of transformer configuration will you select to design a high input impedance and low output impedance amplifier?
main volage
