World University of Bangladesh Dept. of C omputer S cience and Engineering Digital Electronics - I Lab (CS E 606) Prepared by Md. Mukit and Paroma Jahan Experiment No.: 7 Experiment Name: Design and implementation of a Half subtractor and Full subtractor circuits. Objectives: 1. To have idea about how half and full subtractor are constructed using basic gates. 2. To derive the truth table from the constructed circuits and verify the outputs. Apparatus Required: 1. DC Power Supply 2. LED, Connecting Wire 3. The Logic Gates 4. Breadboard Theory and Methodology: A subtractor is also a combinational circuit that calculates the difference of two binary digits. This is done by taking the two’s complement of the subtrahend and then adding it with the minuend. So the subtractor circuit can be designed with the help of adder circuits. Like adders, there are two types of subtractor circuits, half subtractor and full subtractor.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
