This paper presents an equivalent circuit model with source elements for systems containing external field. The coupling effect of the external field is considered with current sources (Is) added to the expression of admittance matrix (Y) of the system. The frequency-domain responses of Y and Is...
Quantum simulators can be investigated within the frequency domain, including quantum random walks48 and Boson sampling46. By varying the number of BS-FWM pumps and adjusting the relative phase and power between them, we can explore a variety of quantum-circuit configurations and interesting ...
The second issue lies in the time domain where the internal switched capacitor front end introduces kickback into the driver circuit. This problem occurs when the converter switches from one mode to the other, charging the input capacitors from the previous sample to the current sample. Therefore,...
An equivalent circuit in complex frequency domain, applicable for both triplen and non-triplen harmonics is given. Computations for steady-state stator currents using this analysis are made, and results compared with those obtained by earlier authors using different method.doi:10.1080/07313568008955407...
There are two ways to specify a discrete filter: in the frequency domain and in the time domain. Frequency specification of the magnitude and phase for the desired filter are more common in IIR filter design, while the time specification in terms of the desired impulse response of the filter...
EIS data can be analyzed using a suitable physical model (e.g., an equivalent circuit) to describe physical or chemical processes in the material/interface. EIS measurement involves applying alternating excitation V(t)=Vmsin(ωt), at frequency f=ω/2π, to the material and measuring resulting...
The “time interval where the signal is concentrated” is given by Δt, which defines an equivalent duration given by: (Δt)2=∫−∞∞t2|x(t)|2dt∫−∞∞|x(t)|2dt. We have the same relationship in the frequency domain with Δf equivalent bandwidth, given by: (Δf)2=∫−∞...
A circuit for adaptive feedback equalization is disclosed. In one aspect, the circuit includes a frequency-domain feedforward filtering section and a feedback filtering section, a s
We introduce an equivalent-circuit element $Z_{m DW}$ based on the theory of interface pinning in random systems, to analyze the contribution of domain wall motion to the impedance of a ferroelectric, as a function of amplitude $E_0$ and... M Becker,CJ Burkhardt,R Kleiner,... 被引量...
