Programmable dual
biquad filters to offer a variety of filters that can emulate the output of the PID loop for advanced motion control tuning and correction.
D-Pro Windows Software makes speaker correction, setting up crossovers, and equalization easy by allowing the user to import multiple speaker response measurement files that are plotted on a graph and visually equalized by manipulating selected
biquad filters using Visual-Handles that can be dragged with a mouse.
The Magellan-PCI motion controller has dual
biquad filters.
The Kerwin-Huelsman-Newcomb (KHN)
biquad has low sensitivity performance, low component spread and good stability characteristics [1], [2].
Continuous-time
Biquad and Ladder Filters are very complex functions that have been burdensome and involved for analog designers.
In this paper, we present structure of the reconnection-less reconfigurable
biquad (second-order) filter based on four OTAs, that allows more types of transfer characteristic and more possibilities of electronic control than previously reported solutions.
