6. Indirect synthesis
In the preceding analog synthesis schemes, the spectral purity of the signal is limited by spurious lines from successive mixtures, which are not sufficiently attenuated by filtering. Indirect synthesis relies on the use of phase-locked loops, which inherently provide highly efficient filtering.
6.1 Indirect analog synthesis
The basic element of this type of synthesis is shown in figure 21. The various signals at frequencies νb + kΔν are injected simultaneously into one of the phase detector (DP) inputs. The signal generated by the VCO is translated in frequency by the mixer M1 pumped...
