| 11. | Mixer circuits are characterized by their properties such as conversion gain ( or loss ), and noise figure.
|
| 12. | The low-noise quality of an LNB is expressed as the noise figure ( or sometimes noise temperature ).
|
| 13. | The noise figure of a valve is inversely proportional to its transconductance; higher transconductance generally means lower noise figure.
|
| 14. | The noise figure of a valve is inversely proportional to its transconductance; higher transconductance generally means lower noise figure.
|
| 15. | Noise figure is not usually an issue for power amplifier valves, however, in receivers using valves it can be important.
|
| 16. | An equivalent definition is : noise figure is the factor by which insertion of the amplifier degrades the signal to noise ratio.
|
| 17. | Some commercial microwave noise generators use avalanche diodes to create a large excess noise figure that can be turned off and on.
|
| 18. | Noise figure in an ideal DFA is 3 dB, while practical amplifiers can have noise figure as large as 6 8 dB.
|
| 19. | Noise figure in an ideal DFA is 3 dB, while practical amplifiers can have noise figure as large as 6 8 dB.
|
| 20. | Noise figure is a measure of the noise produced by a receiver compared to an ideal receiver, and this needs to be minimized.
