Realization of data acquisition channel circulation based on CPLD technology

It is always confronted that the number of data acquisition channels is insufficiency while data(acquiring).Through utilizing the CPLD technology,combining the singlechip with the CPLD and(circulating) the data acquisition channel,the problem of the insufficient data acquisition channel is(effectively) solved.Thus,the new application of the high precision acquisition card is realized,and the(scientific)(breakthrough) in data acquisition is achieved.The result shows that the design is reasonable and easy to(realize),and can be taken as a general solution for the problem of insufficient channels.
