![]() However, using it can save you time in drawing the circuit. ![]() Note that you are not required to use a Mux. Hint: for the circuit of Y you can use a 4-to-1 Mux. 4 +Ĭ) Please draw the logic diagram for a single bit stage. You only need to write down your optimized equations here. An arithmetic circuit is a logic circuit that performs basic arithmetic operations like addition, subtraction, increment, decrement and transfer operations. You can use K-maps to optimize the equations on a scratch paper. Inputs Outputs Si So Ai Bi Xi Yi B) Please write down an optimized equation for X and Yi, respectively. Select S 0 0 1 1 So 0 1 0 1 X A A 0 A Input Y B B' B all Is G Cin=0 Cin=1 G=A+B (add) G=A+B+1 G=A+B' G=A+B'+1(subtract) G=B G=B+1 (increment) G=A-1(decrement) G=A (transfer) A) Complete the following truth table. Draw the logic diagram for a single bit stage. Design a 4-bit arithmetic circuit, with two selection variables Sand So, that generates the arithmetic operations in the following table. In part 1 video two 4-bit numbers are stored in two registers using IC 74LS173.Link to circuit diagram.
