Conic display generator using multiplying digital-analog decoders

The need has been recognized for a computer-driven generator which is capable of drawing complex curves without imposing a great burden on the central computer. It has been shown that analog and hybrid techniques offer promise of lifting some of this computational and storage load. Past approaches using these techniques have been limited in speed and in kinds of curves drawn. Roberts has proposed a hybrid analog-digital generator based on homogeneous coordinate mathematics. Such a generator has been designed and built using the wideband multiplying decoder as its basic component.
