Sometimes, when using a modal impact hammer to calculate an experimental FRF, a user may apply an Exponential Window to avoid leakage effects to the accelerometer signal. The accelerometer response is multiplied the exponential window causing it to decay quicker in time, thus increasing the apparent...
Closed-loop gain and phase plots are well-worn tools used to determine the stability of the control loop in switching regulators. Gain and phase measurements, when done properly, require access to, and familiarity with, fancy network analyzers. The measurements involve breaking the control ...

The poles and zero positions are determined by loop gain and loop phase shift. A positive pole will add –20 dB/dec slope for gain curve in the Bode plot and will add a –90° phase shift for the loop phase curve in the Bode plot. Conversely, a positive zero will add a 20 ...
This graph is essential in control engineering to assess system stability. It features two plots: the Bode magnitude plot, showing response magnitude in decibels, and the phase plot, detailing phase shifts in degrees. In the Bode plot, the corner frequency is defined as the frequency at which ...
