The Synthesis Calculation
The synthesized trace is displayed with the X-axis in Hertz. Consequently, for
H(s), the parameters (such as pole positions) must be in Hertz. The synthesis
equation for H(s) is as follows:
H(s) | s = jw
Since Laplace transfer functions are expressed in radians and the display’s
X-axis is not in radians , it needs to be scaled to Hertz.
If you modify H(s) to express it in Hertz, you must adjust the gain of H(s) to
keep the dc gain constant.
