FREQUENCY PLAN |
摘要 |
A system for transmitting and receiving signals, the system includes the use of a frequency plan table, and a system of creating the frequency plan table. The frequency plan table relates carrier frequency channels to the operation of a synthesizer and a plurality of programmable frequency dividers in a locked loop. In a transmitter, a first programmable frequency divider (708) accepts a reference signal and produces a comparison signal. A mixer (702) accepts the reference signal and a transmission signal and produces a loop signal. A second programmable frequency divider (710) accepts the loop signal and produces a loop signal having a divided intermediate frequency signal. A phase detector (406) compares the comparison signal and the loop signal having a divided intermediate frequency and produces an output that controls a variable controlled oscillator (712). The variable controlled oscillator produces a modulated transmission signal.
