Definition of "class S amplifier" |
sampling or pulse width modulation amplifier in which a sampling circuit (or pulse width modulator), pulse amplifier and a low pass filter are cascaded. The input signal is sampled at a significantly higher rate than the input frequency (this requires a high frequency sampling signal), and the original signal is transformed into a constant amplitude pulse chain in which the pulse widths are proportional to the original signal’s amplitude. The resulting pulse chain is amplified using any of the highly efficient switching methods desired. The output is then demodulated using a low pass filter, replicating the original signal. It is important to note that rapid variations in the input signal amplitude relative to the sampling signal will cause significant distortion or loss of information. |
