ABSTRACT:
Apparatus for indicating proper compensation of an adjustable frequency compensation network comprises a signal source operable to apply a rectangular pulse train having a preselected peak magnitude to the frequency compensation network, and a peak detector circuit for comparing the output voltage of the frequency compensation network to at least one threshold value. The peak detector circuit is used to determine whether, at a time that follows a transition of a pulse of the pulse train by an interval that is less than one time constant of the frequency compensation network, the output voltage of the frequency compensation network bears a predetermined relationship to the threshold value.
