| 11. | FM radio services direct from Melbourne can be received in Colac but signal levels are low.
|
| 12. | Tube amplifiers respond differently from transistor amplifiers when signal levels approach and reach the point of clipping.
|
| 13. | Many circuit elements that operate linearly at low signal levels will show nonlinearity at higher signal levels.
|
| 14. | Many circuit elements that operate linearly at low signal levels will show nonlinearity at higher signal levels.
|
| 15. | With a little modification, the basic precision rectifier can be used for detecting signal level peaks.
|
| 16. | Adding diode logic will degrade the signal level and result in poor noise rejection and possible failure.
|
| 17. | "' Enormous signal level ranges must be accommodated by radio transceiver equipment " '.
|
| 18. | The opposite is usually true of analog systems, where distortion tends to increase at high signal levels.
|
| 19. | Even when all these factors are observed, the resulting signal level is often just above the noise.
|
| 20. | As well as increasing the signal level, the device may be used to provide spatial temperature averaging.
