| 21. | The modulated signal is shown below for a short segment of a random binary data-stream.
|
| 22. | The information from the modulated signal is carried in sidebands on each side of the carrier frequency.
|
| 23. | Multiplicative mixers are often used in conjunction with an oscillator in the communications field to modulate signal frequencies.
|
| 24. | If the demodulating phase is even a little off, it results in crosstalk between the modulated signals.
|
| 25. | If the circuit were not fairly linear, the modulated signal could not be recovered with reasonable fidelity.
|
| 26. | The output signal can be viewed as a product of the input RF signal and the modulating signal.
|
| 27. | Because of the orthogonality property of the carrier signals, it is possible to detect the modulating signals independently.
|
| 28. | This optical transmitter converts the electrical signal to a downstream optically modulated signal that is sent to the nodes.
|
| 29. | When hierarchical-modulated signals are transmitted, users with good reception and advanced receivers can demodulate multiple layers.
|
| 30. | It also has a primitive spectrum analyzer with ?0 channels indication with wave monitoring of received / modulated signal.
