Abstract
A method is contemplated for removing ringing phenomena from a signal impulse which comprises storing amounts of energy or voltage corresponding to amplitude variations of the signal impulse, interrogating said amounts in a delayed manner, and subsequently feeding back the interrogated amounts to the signal impulse. An apparatus is provided for the method which comprises an analog memory including a ring stepping switch including switching contacts, storage capacitors coupled to said contacts and means for interrogating said capacitors. The number of switching steps is determined by the number of the switching contacts and corresponds at least in part to part of the signal impulse passing unchanged through the apparatus. The apparatus further comprises a plurality of storage means for storing respective indicia of magnitudes of sequential sections, impulse interrogating means for sequentially interrogating the storage means with a fixed delay, and means to couple the interrogating means to the storage means in feedback relation.
