| 1. | In an ideal current or transconductance amplifier the output impedance approaches infinity.
|
| 2. | Their output impedances have been intentionally developed to approach zero.
|
| 3. | The circuit topology also affects input and output impedance.
|
| 4. | Gives the small source impedance ( output impedance ) of the power amplifier.
|
| 5. | One can however measure its input or output impedance.
|
| 6. | Characteristically, solid state amplifiers have had much lower output impedances than tube amplifiers.
|
| 7. | Finally, the 2R resistance is in series with the digital-output impedance.
|
| 8. | A LISN provides a measurement port with, usually, 50 ? output impedance.
|
| 9. | Without feedback, this arrangement results in an output impedance of 6 8 ohms.
|
| 10. | The output impedance in that case is:
