Accelerated channel scanning with a two-point-modulated phase-locked loop

Abstract:

A receiver is provided having a two-point-modulated phase-locked loop for the rapid scanning of the signal strength of a plurality of frequency channels. The two-point modulation includes a modulation of a frequency gain by an oscillator in the phase-locked loop and a modulation of a frequency division by a divider in the phase-locked loop.
