we do have a schematic which implements a transfer function as
H(s)= Zeros / Poles
We wanted to implement this as a verilogA model to gain some simulation
speedup.
Therefore we calculated our Zeros & Poles from the schematic,
added these as
Re: Poles an Zeros ... Basically, you can express the behavior of a linear, continuous-time, time-invariant system with a mathematical construct called a "transfer function".... It turns out to be very easy to calculate the response of such a system to a continuous sine wave at a particular frequency -- in this case the poles of a system will tend to make the system gain go down as the frequency is increased, and the zeros will make the gain go up. ... Do you need to implement control loops in software? ... (sci.electronics.basics)

Re: Warping Pole/Zero Plot ... My plots of the frequency response look correct, but the scaling on the y-axis is not the same. ... I find the poles and zeros of this solving the quadratic equation for the denominator and the a simple algebraic one for the numerator. ... I find a new transfer function from this and plot it. ...

optimization of transfer function ... I have magnitude and phase data for given frequencies.... I need to find and optimize the parameters of a transfer function with certain poles and zeros.... (comp.soft-sys.matlab)
Re: filter with arbitrary and variable rolloff ... realized by alternating real poles with real zeros. ... If you plot R.B-J's poles and zeros on log paper, ... if i recall correctly there was some manual adjustment... (comp.dsp)
