Title:
INTERFACE UNIT BETWEEN ANALOG INPUT SIGNAL AND DIGITAL SIGNAL BUSES
Document Type and Number:
Japanese Patent JPS62242261
Kind Code:
A
Abstract:
A unit for providing an interface between analog input signals and a digital data processing system bus includes a plurality of sample-and-hold circuits coupled to the analog input signals, a multiplexer for selecting a particular sample-and-hold circuit, and an analog-to-digital converter for providing a digital signal related to the amplitude of a selected portion of the input signal. A control circuit provides control signals for controlling the operation of the sample-and-hold circuits, the multiplexer, and the analog-to-digital converter circuit. The control circuit can receive and store signals from the data processing system and use such signals to control the operation of the interface unit.
