Feedback (Electronics), Piezoelectric devices
The purpose of this research is to test a unique implementation of active feedback applied to a low frequency piezoelectric transducer. Understanding that active feedback can be used to shape the frequency response of an electrical system a method for applying active electroacoustical feedback will be used to obtain a wider acoustical bandwidth in a piezoelectric transmitter. By applying active feedback to a resonant device its bandwidth was increased by a factor of 2.5. This is a significant improvement for applications where minimum electrical phase shift versus frequency is desired.
