nominal centre frequency of a channel
λ is the wavelength at the nominal centre frequency of the frequency band considered
A band-stop bandwidth of less than 0,5 % of centre frequency
A band-stop bandwidth of less than 0,5 % of centre frequency
a band-stop bandwidth of less than 0,5 % of centre frequency
The frequency controller controls a center frequency for the plurality of center frequencies and selects the center frequency corresponding to the selected transmission center frequency.
A center frequency of the first channel is different that a center frequency of the second channel.
Next, the difference between the measured center frequency and a desired center frequency is determined (504).
