1049 * filter coef n1 = numerator = n1g0*k^0 + n1g1*k^1*(2^x) + n1g2*k^2*(2^x) + n1g3*k^3*(2^x)
1051 *where n1g0, n1g1, n1g2, n1g3 are from the truncated power series expansion on theta
1052 *(k*2^x = theta, but we incorporate the k along with the n1g0, n1g1, n1g2, n2g3)
1057 * so actually, the following coefs listed as n1g0, n1g1, n1g2, n2g3 are really
1060 * n1g2*k^2
1063 * NOTE that n1g0 == n1g1 == 0, always, so we only need to store n1g2 and n1g3
