Abstract

Abstract Control apparatus which includes a memory unit having input means for receiving successive input signals and output means for providing an output signal over periods of time longer than the duration of individual input signals and which is functionally related to the last-received input signal; and storage means for receiving, averaging, and storing the successive input signals. Means are provided for connecting the averaging or storage means to apply the averaged signal stored therein to the input means in response to an interruption in the reception of the successive input signals by the input means of the memory unit.
