ABSTRACT:
A signal which changes from amplitude X to amplitude Z is applied to a resistor of value R which is series connected with an electrical L-C (inductor-capacitor) delay line unterminated at the opposite end and having a characteristic resistance of value R and one-way delay time T. An output terminal is coupled to the junction of the resistor and delay line. For a time duration 2 T after the input signal changes value, a signal of value (X+Z).div.2 appears at the output terminal and thereafter a signal of value Z appears.
