output impedance उदाहरण वाक्य

Output impedance is 50, 500 ohms.
Negative feedback in an amplifier lowers its effective output impedance and thus increases its damping factor.
The actual output impedance for most devices is not the same as the rated output impedance.
The actual output impedance for most devices is not the same as the rated output impedance.
Solving for the output impedance gives:

However, most of these will be improved by lowering output impedance and hence improving damping factor.
The transformation ratio is the ratio of the input and output impedances of the impedance matching network.
Therefore, feedback has no effect on the output impedance, which remains simply " R"
In contrast, modern transistor amplifiers can have very low output impedance, enabling lower-impedance headphones.
The chip also had higher output impedance, requiring heavier external noise filtering circuitry but outputting louder sound.
