A Power Re-Use Technique for Improved Efficiency Robert Langridge,
... Fig. 6 plots the variation in efficiency using a 50% amplitude modulation of the input signal at a 10-kHz rate. In this case, there is little difference between this result and the continuouswave (CW) result of Fig. 3. Even wider bandwidths are required for a CDMA case, where the typical modulation ...

Tube sound
![](https://commons.wikimedia.org/wiki/Special:FilePath/Tubes.jpg?width=300)
Tube sound (or valve sound) is the characteristic sound associated with a vacuum tube-based audio amplifier. After introduction of solid state amplifiers, tube sound appeared as the logical complement of transistor sound, which had some negative connotations due to crossover distortion of early transistor amplifiers. The audible significance of tube amplification on audio signals is a subject of continuing debate among audio enthusiasts.Many electric guitar, electric bass, and keyboard players in several genres also prefer the sound of tube instrument amplifiers or preamplifiers.
