Abstract: In an RF receiver having a phase-locked loop demodulator and FLL tuning in its RF converter, the frequency of the VCO output signal in the phase-locked loop (PLL) demodulator is controlled indirectly by the FLL in the RF converter in response to a measurement of the VCO output signal in the phase-locked loop demodulator and comparison of such measured signal to a predetermined intermediated frequency. A microcomputer performs a refined FLL tuning algorithm to tune a selected RF carrier input signal and audio subcarrier input signals. The algorithm provides a means of assuring that the PLL demodulator is responding to an input signal derived from a carrier signal of a selected input frequency without having to use hardware to detect the presence of a carrier signal.
