In most naturally occurring media, the phase function is a 1D function of the angle θ between the two directions ωo and ωi; these phase functions are often written as p(cos θ). Media with this type of phase function are called isotropic because their response to incident illumination is...
angular multi-intensity alternating projection is also possible. By switching the aperture constraint from the spatial domain to the frequency domain with a lens system, multiple intensity maps with different frequency information are recorded by changing the angle of the incident light...
The transfer function is determined by an amplifier 5 and an impedance network comprising resistors R1, R2, R3, R4 and capacitors C1, C2. When used with a polyphase input signal Fig. 2 (not shown), separate phase comparators are used for each phase, their outputs being combined to provide...
In radar systems, to achieve high-precision multi-dimensional measurement of targets, radar signal generation is a basic and important function. A microwav... Ding-dingLIANG,YangCHEN - 《Acta Electronica Sinica》 被引量: 0发表: 2022年 HYBRID TECHNIQUES FOR INFORMATION TRANSFER USING DISCRETE- FRE...
The negative sign indicates that the output phasor lags behind the input phasor by this angle. Thus: The gain and phase of a system when subject to a sinusoidal input is obtained by putting the frequency response function in the form a + jb and then the gain is √(a2+b2) and the phas...
(a) Fraction of disclinations, (b) fraction of dislocations, (c) order parameter, (d) relative compaction, (e) solid fraction and (f) normalized solid fraction as a function of V-shape angle\(\theta\)and acceleration amplitude\(\Gamma\). (a,b,e,f) are averages over time whereas (...
the system to the verge of instability. The crossover frequency is the frequency at which |G(jω)|, the magnitude of the open-loop transfer function, is unity. The phase margin γ is 180° plus the phase angle ϕ of the open-loop transfer function at the gain crossover frequency, ...
The basic control method of the dual-active-bridge converter involves adjusting the output voltage and power through phase-shift angle control. The single-phase-shift (SPS) modulation stands out as the simplest, involving only one control variable. Consequently, for each determined transmission power...
The following conditions were assumed for the calculations: zero initial conditions, supply voltaged equal to 𝐸1𝑅𝑀𝑆=233E1RMS=233 V, and an initial phase angle 𝜑0=φ0= 0 deg, which are consistent with measurement conditions. The integration interval was limited to two periods of ...
A phase function is an important characteristic of a scattering medium. A method to derive new analytic phase functions is proposed. The relation between a phase function and an angle-averaged single-scattering intensity, derived earlier [M. L. Shendelev
