WebThe impedance spectra generated allows the characterisation of layers, surfaces or membranes. The results of EIS are represented using Bode plots and Nyquist plots (Moisel, de Mele and Müller, 2008). For the Bode plot, the magnitude of the impedance (│Z│) and the phase angle (θ) are plotted against the logarithm of the frequency. In electrical engineering and control theory, a Bode plot /ˈboʊdi/ is a graph of the frequency response of a system. It is usually a combination of a Bode magnitude plot, expressing the magnitude (usually in decibels) of the frequency response, and a Bode phase plot, expressing the phase shift. As originally conceived by Hendrik Wade Bode in the 1930s, the plot is an asy…

Webfrequency, with the proportionality constant being equal to the time delay. – The amplitude characteristic of the Bode plot is unaffected by a time delay. – Time delay always decreases the phase margin of a system. – Gain crossover frequency is unaffected by a time delay. – Frequency-response methods treat dead times exactly. WebThe compensator time constant can now be calculated as τ = 1/ω c2. • Use a −20 dB/dec line starting from the point defined by ω c2 on the high-frequency gain asymptote to the intersection with the 0 dB low-frequency gain asymptote; the intersection point is at the other corner frequency ω c1. laura pickett
