Design a code converter that converts an unsigned number a into its negative 2's complement representation -a. Specifically, the circuit has two inputs: a1 and ao, and three outputs: b1 and bo (the equivalent to -a) and valid, which is 1 when -a can be represented in 2's complement and O otherwise. 1. Write the truth table for the code converter. 2. Give the simplest SOP expressions for the functions b1, bo, and valid.

A Gray code is a sequence of binary numbers with the property that no more than 1 bit changes in going from one element of the sequence to another. For example, here is a 3-bit binary Gray code: 000, 001, 011, 010, 110, 111, 101, and 100. Using three D flip-flops and a PLA, construct a 3-bit Gray code counter that has two inputs: reset, which sets the counter to 000, and inc, which makes the counter go to the next value in the sequence. Note that the code is cyclic, so that the value after 100 in the sequence is 000.

A Sequence Detector is a circuit which given an input string of bits generates an output 1 whenever the target sequence (pattern) has been detected. There are two types of sequence detectors: Overlapping: The detector allows overlapping, hence the final bits of one sequence can be the start of another sequence. Non-overlapping: The detector does not allow overlapping, hence a new sequence starts only after the previous sequence is completed. Ex: Detect pattern 101 For non-overlapping case: Input :0110101011001 Output:0000100010000 For overlapping case: Input :0110101011001 Output:0000101010000 Design a sequential circuit (overlapping) with an input ‘x’. The pattern to be detected is the binary number that is equal to 1001100 For example,the circuit detects the sequence 00010 . When the sequence is detected, the detector outputs z=‘1’ For this circuit: Draw the ASM diagram. Construct the state table. Draw the logic circuit for the datapath and control in logisim.
