4 Bit Binary Full Adder and Subtractor

4 Bit Binary Full Adder and Subtractor .
4- Bit Binary Full Adder and Subtractor or Computer Logic Training Board has been designed specifically for the study of phenomena of addition and subtraction of 4-bit binary numbers using 4-bit arithmetic and complementary techniques. This Training Board uses controlled inverter and full adders to carry out the operations of addition and subtraction. 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.
