Abstract
An improved analog memory arrangement is interfaced to receive digital signals through a digital to analog converter and is interfaced to output analog signals through an analog to digital converter. Analog refreshing is implemented to reduce degradation of analog signals stored by the analog memory including scale factor refreshing and bias refreshing. The analog memory is particularly suitable for illumination signal processing and for storing display images to be displayed.
