Please Like, Share, and subscribe to my channel. Q. 6.9: Two ways for implementing a serial adder (A + B) is shown in Section 6.2. It is necessary to modify the circuits to convert them to serial subtractors (A - B). (a) Using the circuit of Fig. 6.5, show the changes needed to perform A + 2’s complement of B. (b) Using the circuit of Fig. 6.6, show the changes needed by modifying Table 6.2 from an adder to a subtractor circuit. ----------------------------------------------------------------------------------------------------- You can follow me on ---- Facebook: https://www.facebook.com/dhiman.kakati Twitter: https://twitter.com/Dhiman_kakati Instagram: https://www.instagram.com/dhiman_kakati/?hl=en Researchgate: https://www.researchgate.net/profile/Dhiman_Kakati Facebook Page: https://www.facebook.com/Lets-prepare-for-Gate-2021-1569735116397880 Problem solutions of the book Digital Design by Morris Mano and Michael Ciletti: https://www.youtube.com/watch?v=VjinH8aL78I&list=PLI0y8_sKQPD991sipHcqWNOJ0nmCnqPSw&index=165 Online Store: ----------------------------------------------------------------------------------------------------- Wish you success, Dhiman Kakati (let's learn together)
