Abstract: Apparatus for generating a staircase test signal includes means for generating a staircase waveform wherein each step differs in value by the factor x. This generated waveform is then applied selectively to a square root x attenuator circuit to change the value of a portion of each step by the factor square root x, thereby producing a waveform wherein each of the resultant steps differ in value by the factor square root x.
