Two point modulation pll
WebFig. 4 shows the block diagram of phase modulator using two-point modulation. The two-point modulation structure is the same as that used in [17]. Using two modulation points, … WebPLL frequency synthesizers can also be modulated at low frequency and down to DC by using two-point modulation to overcome the above limitation. Modulation is applied to the VCO as before, but now is also applied digitally to the synthesizer in sympathy with the analog FM signal using a fast delta sigma ADC. See also. Superheterodyne receiver
