| 11. | When in 40 MHz mode, the center frequency is actually the mean of the primary and secondary channels.
|
| 12. | To receive a station, an FM receiver is tuned to the center frequency of the station's channel.
|
| 13. | A typical UWB system might use a bandwidth of one-third to one-half of its center frequency.
|
| 14. | In these filters the resonant frequencies of all the resonators are tuned to the passband center frequency f _ 0.
|
| 15. | It allows users to control the amplitude and frequency, but uses a pre-set bandwidth of the center frequency.
|
| 16. | Because each channel is 0.2 MHz wide, the center frequencies of adjacent channels differ by 0.2 MHz.
|
| 17. | The extreme case when the signal at the channel's center frequency is completely eliminated is known as a notch filter.
|
| 18. | A narrow band system, typical of radars, is one where the bandwidth is only a small fraction of the center frequency.
|
| 19. | Being on-key presumes that there is a key center frequency around which some portion of notes have well defined intervals to.
|
| 20. | A sharply tuned filter has good frequency resolution as it allows the center frequencies through but not other frequencies ( Pickles 1982 ).
