  • Electric Motor Power Measurement and Analysis

    Part 3: Electrical Power Measurements for a Three-Phase AC motor. Complete testing of a PWM (pulse width modulation)-based drive and motor system is a three step process. Step 1 is accurate measurement of PWM variable speed drive input and output power, in order to identify drive efficiency and power losses.

  • Surface Acoustic Wave - an overview

    3.2.5 Surface acoustic wave materials. A surface acoustic wave (SAW), also called a Rayleigh wave, is essentially a coupling between longitudinal and shear waves. The energy carried by the SAW is confined near the surface. An associated electrostatic wave exists for a SAW on a piezoelectric substrate, which allows electro-acoustic coupling via ...

    As is true for all waves, there are four main characteristics of a sound wave: frequency, wavelength, period, and amplitude. Frequency is the number of waves per unit of time, and in sound is heard as pitch. High-frequency (≥15.000Hz) sounds are higher-pitched (short wavelength) than low-frequency (long wavelengths; ≤100Hz) sounds.
