Bode diagram

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 accuracy of flux-linkage stabilization is determined by the spread of the curves of its modulus of transient processes, and the stability reserves by amplitude and phase--according to the Bode diagram at various random variations of the undefined parameters of the regulator k, [k.sub.1], [k.sub.2], [k.sub.3], [T.sub.1], [T.sub.2] and the object [K.sub.fc], [R.sub.1eq], [R.sub.2], [L.sub.1], [L.sub.2], [L.sub.12] within specified boundaries.
