Mar 16, 2015 · Besides above there are also university professors giving lectures on scalar waves. Here is a video of Gregory Durgin at Georgia Tech giving a lecture on scalar waves: WAV02: The Scalar Wave Equation (48min 54sec) And here is a video of Jamesina Simpson at University of Utah: FDTD Lecture 1a: Scalar Wave Equation (Setting up the Problem) (10min ...

May 21, 2012 · Sinusoidal waves don't have harmonics because it's exactly sine waves which combined can construct other waveforms. The fundamental wave is a sine, so you don't need to add anything to make it the sinusoidal signal. About the oscilloscope. Many signals have a large number of harmonics, some, like a square wave, in theory infinite.

Feb 3, 2019 · While learning 3-Phase scalar control of ACIM using STM32F407 MCU I could not clearly understand the diffrence between the following terms: 1. SPWM 2. 6-step PWM 3. SVMPWM How do they differ from ...

First, let us say that the complex plane is an immediate consequence of the introduction of the embarrassing symbol j (or i in mathematics).

Oct 12, 2012 · A scalar processor executes at most one instruction per cycle, super-scalar means it can potentially execute more than one instruction per cycle. For example, if the processor has a functional unit for integer arithmetic and another for floating point then why not use both at the same time to execute two instructions simultaneously.

Radio waves are produced when the electric field rapidly changes: there has to be an alternating current. An electric field spreads out into space. When you change an electric field, the distant parts of it do not change instantly.

Aug 17, 2012 · What you are apparently thinking of is wavelengths so short that the energy is very high, like xrays and gamma rays. These go thru things solely because of their high energy. At lower energies (longer wavelengths), the waves interact with the material in various ways so that they can get absorbed, refracted, reflected, and re-emitted.
