... The content of the higher harmonics voltage (current) and electromagnetic interference generated in the inverter fed drive depends on the modulation technique. Therefore, PWM methods are investigated from this point of view. To reduce these disadvantages several methods have been proposed. One of th ...

... If a function f (x) is not continuous at a point c, we say that f (x) is discontinuous at c and call c a point of discontinuity of f (x). The Continuity Test The function y=f(x) is continuous at x=c if and only if the following statements are true:1. f (c) exists (c lies in the domain of f). 2. lim ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
