Band-pass transfer function design sample using FAZA.

Input parameters:

Fstopleft = 2.0*10^6 (rad/sec)

Fpassleft = 3.0*10^6 (rad/sec)

Fpassright = 5.0*10^6 (rad/sec)

Fstopright = 6.0*10^6 (rad/sec)

Astopleft = 50 (db)

Apass = 2 (db)

Astopright = 50 (db)

Approximation method: Chebyshev

Filter properties:

Filter's order: 12

Nominator's degree: 6

Denominator's degree: 12

Transfer function H(s) = P(s)/Q(s)

Transfer function nominator P(s):

P(s) = S^6 * 2.61512e+036

Transfer function denominator Q(s):

Q(s) = 1.13906e+079 + S^1 * 1.06499e+072 + S^2 * 4.90979e+066 + S^3 * 3.78405e+059 + S^4 * 8.56429e+053 + S^5 * 5.21155e+046 + S^6 * 7.73012e+040 + S^7 * 3.47437e+033 + S^8 * 3.80635e+027 + S^9 * 1.12120e+020 + S^10 * 9.69838e+013 + S^11 * 1402451.414 + S^12 * 1.0

Factored form of transfer function:

P(s) = 2.61512e+036*s^6

Q(s) = 1.0*(s^2 + s*1.17031e+005 + 2.47730e+013)*(s^2 + s*7.08618e+004 + 9.08244e+012)*(s^2 + s*3.03517e+005 + 2.16989e+013)*(s^2 + s*2.09816e+005 + 1.03692e+013)*(s^2 + s*3.74395e+005 + 1.71830e+013)*(s^2 + s*3.26830e+005 + 1.30943e+013)
