   a bode plot  is a graph of the transfer function of a linear, time-invariant system versus frequency, plotted with a log-frequency axis cavitation, to show the system's frequency response. it is usually a combination of a bode magnitude plot, expressing the magnitude of the frequency response gain, and a bode phase plot, expressing the frequency response phase shift. == overview == among his several important contributions to circuit theory and control theory, engineer hendrik wade bode (1905â1982), while working at bell labs in the united states in the 1930s, devised a simple but accurate method for graphing gain and phase-shift plots. these bear his name, bode gain plot and bode phase plot. "bode" is pronounced   ().van valkenburg, m. e. university of illinois at urbana-champaign, "in memoriam: hendrik w. bode (1905-1982)", ieee transactions on automatic control, vol. ac-29, no 3., march 1984, pp. 193-194. quote: "something should be said about his name. to his colleagues at bell laboratories and the generations of engineers that have followed, the pronunciation is boh-dee. the bode family preferred that the original dutch be used as boh-dah." the magnitude axis of the bode plot is usually expressed as decibels of power, that is by the 20 log rule: 20 times the common (base 10) logarithm of the amplitude gain. with the magnitude gain being logarithmic, bode plots make multiplication of magnitudes a simple matter of adding distances on the graph (in decibels), since : \log(a \cdot b) = \log(a) + \log(b).\ a bode phase plot is a graph of phase versus frequency, also plotted on a log-frequency axis, usually used in conjunction with the magnitude plot, to evaluate how much a signal will be [[phase (waves)
