摘要：The invention relates to a demodulator to demodulate frequency-modulatedsignals FM including a phase locked loop PLL including at least a phase detector, a loopfilter and a voltage controlled oscillator function VCO', characterized in that said voltagecontrolled oscillator function VCO' has modifiable gain. The invention allows to eliminatedrawbacks presented by the conventional use of a complex gain modifiable amplifier atthe input of demodulated signal processing means. Application: demodulation ofmodulated signals: wireless phone, home network.
