Universal signal generator and signal parameter comparator

Abstract

Abstract A novel universal signal generator is disclosed comprising a composite system including a library or bank of signals consisting of pre-recorded signals of desired form which may be selected as the output of the apparatus. The output of the library or bank of signals may be varied in a manner which is permutated, systematic, random, jittered or wobulated, or in accordance with a predetermined mathematical curve. The output of the bank or library of signals, either as is or as modified, may be fed through a suitable correlator and/or a power spectra density comparator. The signal output, as is or as modified, or the output from the correlator or the power spectra density comparator may be modified by a suitable secondary modulator or second signal generator. A recording mechanism is provided for amplifying and recording a signal from within the system on separator recording tracks in both a forward and reverse direction. A recording means is provided for recording the signal from the recorded tracks and the auto-correlation, cross-correlation, and/or retrocorrelation functions or these recorded signals. The record of these correlations may be of a member, set, or ensemble of the signal components. The output signal from the apparatus may be drawn from any of the aforementioned components with the result that the apparatus is capable of producing a signal which is systematic or random in virtually any desired manner, or signals which may be of virtually any combination of systematic and random forms.
