Abstract
A novel variable resistive network is disclosed enabling the control of an odd number of signals wherein a selected one of said signals is held at a common reference level while others of said signals are varied in amplitude such that no one signal reaches a maximum input level amplitude at the same time as any other of said signals. Method and apparatus for achieving a color presentation from a video signal which may have no color content of its own is taught employing said variable resistive network for Hue control and using dual-input amplifiers having a weighted gate signal for Saturation control.
