Why all the oscillations found in nature mechanical electrical etc are sinusoids?
The sine wave is the curve that naturally occurs when the restoring force is proportional to the displacement. The math is a little complicated (the sine wave in this case is the solution of the corresponding differential equation), but the point is, this relationship between the force and the displacement is a fairly common situation.
What is the concept of complex frequency in basic circuits?
Complex frequency is utilized in electric circuits in order to simplify the math, essentially. It is very similar to the use of phasors, except complex frequency can cover all types of inputs, not just sinusoids.
What is the difference between vector and phaser diagram?
A(t) = Am sin(ωt ± Φ) representing the sinusoid in the time-domain form. But when presented mathematically in this way it is sometimes difficult to visualise this angular or phase difference between two or more sinusoidal waveforms so sinusoids can also be represented graphically in the spacial or phasor-domain form by aPhasor Diagram, and this is achieved by using the rotating vector method.Ansh
How do you generate unipolar sinusoidal pulse width modulation from a function generator?
If you're going to use a function generator, presumably you'll be natural sampling a sinusoid for SPWM. In order to generate unipolar spwm, you'll need two sinusoids that are 180 degrees apart. So take the output of your sinusoid into two unity gain buffers, one inverting and one non-inverting. This will also allow you to set your reference for the sinusoids as compared to the (ONLY ONE!) sampling waveform, which can either be a triangle or a sawtooth. A sawtooth can easily be generated using a single comparator, by the way. One side of the bridge driven from the buffered sample ouptut and the other from the inverted and buffered sample output. It is my understanding that unipolar spwm has the advantage of higher order harmonics, as compared to bipolar, which makes them easier to filter out. The tradeoff is greater complexity because of the required extra input waveform. Good luck.
