| 21. | Only radios that are capable of receiving subcarrier channels can pick up such programming.
|
| 22. | Such services are carried on subcarrier channels.
|
| 23. | The resulting subcarrier sidebands is also known as " chroma " or " chrominance ".
|
| 24. | In subcarrier relative to a reference oscillator.
|
| 25. | WYQS operates at only 100 watts, but is available on WCQS'HD subcarrier.
|
| 26. | This device examines the subcarrier signal and detects the command message that it is carrying.
|
| 27. | All that does is to provide a zero degree phase sample of the colour subcarrier.
|
| 28. | In NTSC, the chrominance sine wave has the same average frequency as the subcarrier frequency.
|
| 29. | The above process uses the subcarrier.
|
| 30. | Frequency ( subcarrier ) interleaving increases resistance to frequency-selective channel conditions such as fading.
