Automatic Tuning of Continuous Time Adaptive Bandpass Filter

A complete new adaptive tuneable filter system is designed and simulated. This is based on controlling the centre frequency (f o ) and quality factor (Q) of a bandpass filter through two electrical tuning circuits. The two circuits automatically correct the filter parameters, via variable resistors,...

Beschreibung
Zusammenfassung:	A complete new adaptive tuneable filter system is designed and simulated. This is based on controlling the centre frequency (f o ) and quality factor (Q) of a bandpass filter through two electrical tuning circuits. The two circuits automatically correct the filter parameters, via variable resistors, in order to adjust f o and Q of the circuit. High accuracy and performance are achieved since this adaptive filter is tuneable against fabrication tolerances and aging. The system is fully simulated using Matlab/Simulink package.
