Bode diagram

[′bōd ‚dī·ə‚gram]
(electronics)
A diagram in which the phase shift or the gain of an amplifier, a servomechanism, or other device is plotted against frequency to show frequency response; logarithmic scales are customarily used for gain and frequency.

The total impedance at low frequencies in the Bode plot has decreased to an even lower value.
For several waveforms with the same peak voltage but different rise and fall specifications, the first breakpoints in the Bode plot lie on the same -20-dB/ decade line.
The left-hand side is the classical Bode plot of the error amplifier absolute gain vs.
This display is known as a frequency response function (FRF) and is commonly shown as a Bode plot. Here, the analyst needs to consider the dynamic range required to observe the resonances and antiresonances.
Although the impedance diagrams apparently look like a slightly depressed single capacitive semicircle, the Bode plot and the equivalent circuit analysis (see below) suggest that in all cases the Nyquist diagram actually consists of two, closely overlapped, time constants.
These three parameters are often plotted on what is known as a Bode plot, shown in Figure 2A.
"It uses the built-in PicoScope signal generator to step through a range of frequencies and DFT extraction to produce a Bode plot of the DUT gain in dB and phase in degrees."
A representative Bode plot of each sample type, obtained from electrochemical impedance spectroscopy (EIS) measurements, can be seen in Figure 3, where samples were exposed in saturated Ca[(OH).sub.2] solution, and in Figure 4 where samples were exposed to a chloride containing Ca[(OH).sub.2] solution.
The Bode plot comparison between the transfer functions with the SSA and the CA methods ((30) and (64)), and the simulated circuit power stage (PS), is shown in Figure 6, for [d.sub.1] = 0.3, 0.5, and 0.7.
The results are also supported by the Bode plot with the relation between frequency and phase angle, indicating the time constants exit two values.
