is the squarer parameter. Thelowpass filterat the summing circuit output effectively integratesvL(t) over a bit period. If 2(fs−fLO)≪BTand the difference between the signal and local oscillator phase noise is small within a bit period, then the input voltage to the decision circuit is...
But as we have already argued in the previous section, this is only true for the closed system. Let us therefore now rederive the low-energy approximation of the QPS Hamiltonian keeping phase compactness, according to Fig. 3b. Here, the phase difference φ does not change as a consequence ...

We have seen that if we multiply two sine waves of the same frequency, the DC value of the product is proportional to the cosine of the phase difference φ between them (Eq. 8.25). We can, therefore, calculate the product as a function of delaying one of the waveforms with respect to...

They measured the etched fracture roughness using a 3D laser microscope and claimed that the average difference in roughness between natural fractures and etched fractures is 11.6%. The roughness produced by the laser etching machines, however, depends on the material, the ratio of the fracture ...
It has a significant meaning in precise measurement. Compared to high-resolution dual mixer time difference method which is widely used in the international, there are the advantages of simple circuit structure, low development cost, small phase noise, quick response time , high authenticity and ...
