Question

Student ID K-map to simply the function f e and "d" is the least si (3 points each) CO: 3] 3. Five bits of information and a parity bit are to be transmitted on a noisy channel. The transmittor a. the parity checker circuits using Only 3-imput logic gates where the unused inpunts)-if any- must be connected to either O or 1, as appropriate. (show the cireuit). (3 points for each circuit for a total of 6 points) ver have agreed to communicate using odd parity, Design both the parity generator and Party Checker Circuir Parity Gemerator Circmir B(A b. A and B are each 2-bit binary numbers. We would like to perform the operation A divided by B). In addition to the result of the division, an error bit, E is equal to 1 whenever B is zero to indicate an error and that the result is not valid. Show the truth-table of the combinational divider circuit. (Note: do not design, only show the truth table) Show the circuit for a single-digit BCD adder using two 4-bit adders and additional logic gates. Show all connections. c. 4. (3 points each) [CO: 4] How many active-high 2x4 decoders (with a single active high-enable and no additional logic gates) are needed to design a 4x16 decoder? (Multiple choice, circle one) i.4 iv. 16 Fall 2017, Sec0l P2/4
