Example Design a Sequence Detector. Specifications: Design a circuit that receives a sequence of bits one by one. Each bit is received at the beginning of each clock pulse. The circuit has one output bit Z , where Z = 1 when the sequence of “1101” has been received, and Z = 0 otherwise. Let’s consider a sequence of input bits: 0 0 0 ...
