Abstract :
A simple method for tuning a state-variable bandpass filter over more than one octave without serious loss in the Q-value is presented. This is accomplished by modifying the input stage by adding one extra variable resistor. Analytical calculations show that there will be a 6% loss in quality factor over the tuning range.
