t(s)= [2(s^2+9.32)] / [s^4+1.322s^3+0.976s^2+.750s+1]

how do you calculate the reate of attenuation increase in db per decade at high frequency?

Determine the gain in db at dc. To do this, just replace s=0 and then do 10log(result) right?

Also, at which freq is the attenation infinite? Is it when the denominator = 0?

Thanks:tongue:
