A novel voltage-mode multifunction biquadratic filter with one input and six outputs is presented. The proposed circuit can realize inverting and noninverting low-pass, bandpass, and high-pass filters, simultaneously, by using two inverting second-generation current conveyors (ICCIIs), two grounded capacitors, and four resistors.

In signal processing, a digital biquad filter is a second order recursive linear filter, containing two poles and two zeros. "Biquad" is an abbreviation of "biquadratic", which refers to the fact that in the Z domain, its transfer function is the ratio of two quadratic functions: = + − + − + − + − The coefficients are often normalized such that a 0 = 1.

In this article, we study this circuit's properties and design issues. The biquadratic filter constants are computed based on user-provided parameters (filter type, center/corner frequency, Q, gain). The process is deterministic and relatively simple (here is a reference), and the function "reconfigure()" in this source file shows a typical embodiment.
