Claim 1
Independent Claim

PROCESSING CIRCUITS FOR THE ELIMINATION OF RELATIVELY SHORT DURATION, SPURIOUS SIGNALS WHICH DIFFER FROM THE SIGNALS NORMALLY PROCESSED BY AMPLITUDES FALLING OUTSIDE THE RANGE OF AMPLITUDES OF NORMAL SIGNALS, SAID CIRCUITS COMPRISING, (A) SIGNAL SOURCE PROCESSING CIRCUITS PRODUCING AN OUTPUT SIGNAL FROM INPUT SIGNALS OF A PREDETERMINED AMPLITUDE RANGE, OF COMPARATIVELY LONG DURATION (B) ELECTRONIC MEANS FOR CLAMPING THE OUTPUT OF THE PROCESSING CIRCUITS TO A PREDETERMINED VOLTAGE LEVEL, AND (C) SAID CLAMPING MEANS BEING ACTUATED BY ELECTRONIC MEANS RESPONSIVE TO COMPARATIVELY SHORT SIGNALS OF AN AMPLITUDE DIFFERING FROM THE RANGE OF AMPLITUDES OF NORMAL SIGNALS BY A PREDETERMINED AMOUNT.
