... The power amplifier efficiency of an amplifier, defined as the ratio of power output to power input, improves (gets higher) going from class A to class D. In general terms we see that a class A amplifier, with dc bias at one-half the supply voltage level, uses a good amount of power to maintain bias ...

0. Basic Audio Terminology Wave Concepts
... A sine wave is most basic waveform and is the building block of harmonic analysis. This is because a sine wave has no harmonics (overtones) at all. It only has the tone of the fundamental frequency without timbre. Triangle wave sounds (and looks) a bit like the sine wave but has some hollow-sounding ...

Single-pulse coherent anti-Stokes Raman scattering microscopy
... Coherent anti-Stokes Raman scattering (CARS) is a nonlinear Raman process in which pulsed light of at least two frequencies is mixed within a sample. By temporally and spatially overlapping the pump light at a frequency of ωp and Stokes light at ωs, CARS light at a frequency of 2ωp-ωs is produced. W ...
