Amplifier design for an implementation of motional feedback in a bass loudspeaker

The displacement of a loudspeaker cone is not linearly proportional to the voltage/current at its input provided. This is due to electrical and mechanical limitations. The distortion is more noticeable at lower frequencies. This report is one of two reports, that will explain how to minimize this distortion. The motion of the loudspeaker cone...

Amplifier Design in a Motional Feedback System

The quality of audio amplifiers used in Hi-Fi sound installations is largely determined by the distortion of the output signal. This report proposes a method of improving the distortion reduction in audio amplifiers by using a topology with active feedback. The characteristics of the standard non-inverting amplifier are extended to this new...
