Ct transfer function

WebThe transfer impedance has transfer zeros at s = ±j1 and s =±j2. Both z 11 and z 12 have the same poles. There are no private poles in z 11; the functions are ratios of even and odd polynomials, zeros, and poles of z 11 interchange. Thus, all … WebThe modulation transfer function, or MTF, is a parameter used to evaluate the performance of a lens. MTF provides a quantitative and standardized way to characterize optical systems, so the metric is used by optical designers and microscopists alike to compare lenses and determine the ideal one for an imaging system.
