quick overview :

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. Object:
