Amplitude modulation is not commonly associated with effective amplifying. This work
focuses on implementing amplitude modulation into a high efficiency Class E amplifier.
Different types of amplifiers are compared with ...
In view of the energy consumption problems, an impact study, extensive laboratory tests and an investigation towards comparable energy saving light sources was carried out on the light sources identified in the survey ...
