PHASE LOCKED LOOP DEMODULATOR WITH GAIN CONTROL |
摘要 |
<p>The invention relates to a demodulator to demodulate frequency-modulated signals FM including a phase locked loop PLL including at least a phase detector, a loop filter and a voltage controlled oscillator function VCO', characterized in that said voltage controlled oscillator function VCO' has modifiable gain. The invention allows to eliminate drawbacks presented by the conventional use of a complex gain modifiable amplifier at the input of demodulated signal processing means. Application: demodulation of modulated signals: wireless phone, home network.</p> |
