| 31. | They are typically used for simple carrier recovery schemes or as the initial method of coarse carrier frequency recovery.
|
| 32. | At the same time as AM radio began, carrier frequencies, called " frequency division multiplexing ".
|
| 33. | Some stations, for instance Droitwich transmitting station in the UK, derive their carrier frequencies from an atomic clock.
|
| 34. | The BVU 800 series Y-FM carrier frequency was upped to 1.2 MHz giving it wider bandwidth.
|
| 35. | Carrier frequencies on the longwave band are assigned as integer multiples of nine kHz ranging from 153 to 279 kHz.
|
| 36. | A carrier frequency of at least ten times the desired output frequency is used to establish the PWM switching intervals.
|
| 37. | Carrier frequency and phase recovery as well as demodulation can be accomplished using a Costas loop of the appropriate order.
|
| 38. | The other meaning of the term " channel " in telecommunications is seen in the phrase " carrier frequencies ".
|
| 39. | Hence, "'carrier frequency offset "'always exists even if there is no Doppler effect.
|
| 40. | This phenomenon can be overcome by shifting the location of the communicating nodes or by switching the communication carrier frequency.
