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.
Do you have high impedance test light?
no
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.
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 difference between high impedance busbar protection scheme and low impedance busbar protection scheme?
high impedance circit provides a varistor unit which has stabilising resistor which ll protect the relay from being operating for maloperations like through fault, CT faults whereas this varistor unit is provided internally in an numerical relay where the CT of class 5P can be used.
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 are the main differences between FETs and BJTs in terms of input impedance?
FET has very high input impedanceBJT has very low input impedance

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.
What is the difference between Low OHIMC Distribution and High OHMIC Distribution?
Low OHIMC (Open High Impedance Microphone Circuit) distribution typically refers to a scenario where the circuit has a higher input impedance, resulting in less loading on the microphone and improved sensitivity, making it suitable for capturing quiet sounds. In contrast, high OHIMC distribution involves lower impedance, which can lead to greater noise and distortion but may be necessary for specific applications where robust signal strength is crucial. The choice between the two depends on the desired audio quality and application requirements.
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.
