WebB. Bode Plot Review Usually in a transfer function V o/V inhas a value at each applied frequency. We use db for the transfer function magnitudes, as it will allow for easy asymptotic approximations to the curves. 1. db values ” 20 log 10G To employ a db scale we always need a BASE value. WebBode plot and Nyquist plot The two notations are the origin of the two most popular plots for impedance spectra: the Bode plot and Nyquist plot. More information is given here: Bode and Nyquist Plot. Figure 1.2 Impedance Z as the real part of impedance Z’ (resistance) and imaginary part Z” For many practical problems, the detailed Bode plots can be approximated with straight-line segments that are asymptotes of the precise response. The effect of each of the terms of a multiple element transfer function can be approximated by a set of straight lines on a Bode plot. This allows a graphical solution of the overall frequency response function. Before widespread availability of digital computers, graphical methods were extensively used to reduce the need for tedious calc… lawyers career information
