Несущая частота определяется так: The RF carrier frequency can be calculated as follows:
fcarrier = (fb+24+(fc+fo)/64000) x 10000 x (hbsel+1) + (fhch x fhs x 10) [kHz],
where parameters fc, fo, fb and hb_sel come from registers 73h–77h. Parameters fhch and fhs
come from register 79h and 7Ah.
А девиация частоты определяет, в каких пределах +/- от несущей частоты будет изменяться частота сигнала при ЧМ модуляции:
When using frequency modulation the carrier frequency will deviate from the nominal center channel carrier frequency by ±Δf:
Δf = fd[8:0]x625Hz
The Frequency Deviation (Δf) is controlled by the Frequency Deviation Register (fd), address 71 and 72h, and is independent of the carrier frequency setting.
