Sine wave generator with phase angle controlHigginbotham John W
n = 0:99; x = sin(pi ∗ n/2) + 0.1 ∗ randn(1,100); % sine plus noise X = fftshift(fft(x)); % fft of signal X1 = abs(X); theta = angle(X); % magnitude and phase theta1 = theta. ∗ X1/max(X1); % masked phase L = length(X); w = 0:2 ∗ pi/L:2 ...
Rays travel perpendicularly to the wavefront (phase normal). (a) Wavefront in real space; (b) WDF in phase space; (c) light field in position-angle space. It is more complicated when the field is not strictly coherent. Generally, the phase-space WDF constitutes a rigorous and non-...
D/A1 to D/A3 : Select any 3 from channel or sum value for Voltage, Current, Active power, Apparent power, Reactive power, Power factor, Phase angle, Total harmonic voltage/current distortion, Inter-channel voltage/current fundamental wave phase difference, Voltage/current crest factor, Time ...
Multiply 360 (to represent the total number of degrees possible in an angle) by the frequency of your wave. Multiply the number that you receive after multiplying the first two variables by the time delay that was given above. When all of these numbers are multiplied together, you will find...
(FT), one can select the +1st or −1st order beam and move it to the baseband. By applying an inverse FT, the object beam can be recovered. One has to be careful, however, not to exceed the Nyquist limit on the camera as the angle between reference and object increases. Moreover...
The GA technique in48 is implemented to find the optimal switching angle of the proposed modified SPWM control scheme, described in the “Modified SPWM technique for MLI” section, implementing the fitness function indicated by Eq. (20). The starting population of chromosomes that implies the ...
• Check that both ElecTheta and rg1.Out are of saw-tooth wave shape and have the same period. If the measured angle is in the opposite direction, then change the order of motor cables connected to the inverter output (TB3 for HVDMC kit). • Qep1.ElecTheta should be slightly ...
The value of the counter is increased successively until the angle passes again from positive to negative. This means that half of rotation of the trajectory has been reached and the angular distance between the starting point and the current point is ππ. Let this number be 𝑁𝑘1Nk1. ...
To solve the problem of the large size of traditional industrial frequency phase-shift transformers and the harmonic distortion of multi-pulse wave rectifier systems, this paper proposes a three-stage shunt zigzag power electronic phase-shift transformer based on a double-tap multi-pulse wave rectifie...
