Summary:Waveform generating apparatus for synthesizing a non-linear waveform by sampling voltage levels along a series string of resistances. The series string of resistances is a linear resistance fabricated in a monolithic integrated circuit structure and includes a series of contiguous resistance elements of approximately the same physical configuration and of approximately equal resistance value. Each resistance element has a projection or nub. Particular ones of the nubs serve as source regions for MOS switching transistors at the sampling point. The intervening nubs are unconnected. The symmetry of the structure compensates for errors otherwise introduced by the presence of source region nubs at sampling points spaced in a non-linear relationship.
