The proposed mixing architecture is described in detail; the method of local oscillator signal frequency selection and the applicable conditions of the proposed structure are derived through math formula; and the conclusions are demonstrated by experimental results.doi:CNKI:SUN:ZYGB.0.2019-04-002Yu ...
Let us consider also the case of a non-linear ODE such as the van der Pol oscillator given as x″+α(x2−1)x′+x=0,α>0. The standard first-order form of it is (x′=y,y′=−x−α(x2−1)y). Using polar coordinates x=rcosθ, y=−rsinθ, this non-...
A mode lock Ti-sapphire oscillator (Coherent Vitesse, 100 fs, 80 MHz) was used to seed the amplifier. The probe pulses were a white light continuum generated by passing the 800 nm femtosecond pulses through a 2 mm CaF2 plate for UV part (250–650 nm). GIWAXS The GIWAXS measurements ...
(2.47) Here, we have usedp=1/2(other valuesp>0give the same conclusion) and that, due to the high frequency cutoffωcinJ[see (2.28)], the integration is essentially overω≤ωc, and thereforecoth(βω/2)≈2/βωprovidedβωc≪1. ...
In this paper, the complicated nonlinear dynamics of the harmonically forced quasi-zero-stiffness SD (smooth and discontinuous) oscillator is investigated
leading to the rise time formula of to(l -cos @/cos 0 in [l] are based on a single scattering result and the rise time is probably lower than the rise time encountered in multiple scattering situations. However, we note that our data in Fig. 2 show an angle dependence that is approx...
(explained below). Thus, the frequency offset is the difference between the GPS satellite oscillator frequency, which is very stable at 1.575 GHz, and the GPS receiver frequency. Using the time and frequency offsets as well as the decoded GPS data, the GPS receiver can efficiently compute its...

Since the oscillating frequency of the oscillator 60 shown in FIG. 11 is selected to be 100 MHz, 1 count value corresponds to 2 m. At a step S3, a delay correction is made to the calculated distance "L", which is caused by modems employed in the station. Then, a check is made ...
A lower frequency clock (Rt_clk) may be received on an input to the SoC 10 (e.g. for the external clock source 434). The external clock source 434 may be a “high quality” clock source such as, e.g., a crystal oscillator. Clock quality may be measured in a variety of ways, ...
