Unformatted text preview: UCLA Department of Electrical Engineering EEM16 – Fall 2011 Discussion2 Solution 1. Ex 2.3 2. Ex 2.11 3. Combinational Logic Design: Write the (i) high-level description, (ii) truth table, and (iii) one-set and zero-set for each of the three functions described by the following specifications. a. A 2-bit-wide shifter takes two input signals, i and i 1 , and shifts them to two outputs, o and o 1 , under the control of a SHIFT signal. If this signal SHIFT is false, then the outputs are equal to their corresponding inputs. If SHIFT is true, then o 1 is equal to i , and o is set to 0. b. A 1-bit demultiplexor takes an input signal IN and “routes” it to one of two outputs, o and o 1 , under control of a single SELECT signal. If SELECT is 0, then o has the value of IN and o 1 is a 0. If SELECT is 1, then o 1 has the value of IN and o is a 0. c. A combinational system takes a decimal digit as input, increments it by one and outputs 10’s complement of the result. 4. Determine whether or not the following expression is valid, i.e., whether the Determine whether or not the following expression is valid, i....
