| 1. | The bandwidth of a filter is proportional to its center frequency.
|
| 2. | The FDM modem operates with a center frequency of 1500 Hz.
|
| 3. | This is the bandwidth of a device divided by its center frequency.
|
| 4. | The center frequency of each band can not be adjusted.
|
| 5. | The center frequency can be adjusted over a several-octave range.
|
| 6. | All of these are channel center frequencies.
|
| 7. | In most cases, a receiver's input band is wider than its IF center frequency.
|
| 8. | This is directly related to the second phenomenon : the waveform on the center frequency becomes less distorted.
|
| 9. | CAM-D does not produce interference on any channels 10 kHz or more from the center frequency.
|
| 10. | Each line feed covered a narrow frequency band : 2 5 % of the center frequency of the band.
