In this recitation, you may help the students with some more advanced combinatorial circuit design: 1. You may ask them to design a 4-bit encoder, which takes four bit inputs and output two bits. If the input bits are 1xxx, the output is 11. If the input bits are 01xx, the output is 10. If the input bits are 001x, the output is 01. If the input bits are 0001, the output is 00. The answer is (please help me double check it)

Unformatted text preview: O1 = I3 | I2 O0 = I3 | (~I2 & I1). 2. Assume that X consists of 2 bits, x1 x0, and Y consists of 2 bits, y1 y0. Write logic functions that are true if and only if X < Y, where X and Y are thought of as unsigned binary numbers The answer is (please help me double check it) O = (~x1 & y1) | (~x1&~x0&y0) |(~x0&y1&y0) Both questions can be solved by K-map....
