filter with R = 1 Ohm and C = 1 Farad. Other R and C values scale the frequency linearly, in inverse proportion; that is, doubling R or C will halve W...
double r, theta=0.f; float step = 2*PI/NUM_PTS; float s, c; while(theta < 2*PI) { s = sin(theta); c = cos(theta); r = sqrt(s * c / (pow(s,4) - pow(c,4)));...
