If the gain of the second-order filter is kept at 1.586, the gain will down 3db for each part. So, the overall gain will down 6dB at the cutoff frequency. By increasing the voltage gain of the second-order filter, we can offset the cumulative loss of voltage gain. bain bebe 1 an

"WebImplement your filter as cascaded second-order sections in the order from step 5. In digital filter vernacular, a second-order IIR filter is called a "biquad" for two reasons. First, the filter's z-domain transfer function includes two quadratic polynomials. Second, the word biquad sounds cool. " - Iir second order filter
