Digital to Analog Converter .
Computer Logic Training Board has been designed specifically for the study of Digital to Analog Conversion(D to A) and to make the students familiar with the basic principle & techniques of “Digital to Analog Conversion”. Input state switches with storage register are provided to feed the derived digital input and analog output can be read directly on a voltmeter in terms of voltage. The board is absolutely self contained and requires no other apparatus. Practical experience on this board carries great educative value for Science and Engineering Students.
