| This paper describes a digitally programmable current-mode universal biquadratic filter. |
|
| It can realize all the standard types of biquadratic functions from the same topology. |
|
| We develop a rational biquadratic G1 analogue of the non-uniform C1 B-spline paradigm. |
|
| Using biquadratic approximations to the local surface, the Gaussian and mean curvature are computed to identify the peaks and pits. |
|
| The characteristic equation is biquadratic and thus contains 14 explicit roots. |
|
| The proposed biquadratic structure is realized using 0.35 µm CMOS technology, and, circuit functionality is verified by SPICE simulations. |
|
| Image Resize proposes also an innovating method: the biquadratic method which is a good compromise between quality and speed. |
|
| For system based optimization, Austin used biquadratic polynomial models of chillers and cooling towers to optimize the condenser-water temperature setpoint. |
