Principles and Realization of Motional Feedback (French)
A closed-box loudspeaker system with motional feedback is considered as a second-order low-pass filter. The study of the stability leads to the use of a second-order high-pass filter in the feed forward path. A realized system is described, using an electrodynamic velocity pickup transducer with high linearity. Circuit diagrams of the amplifier and results from measurements are given.
