A pattern recognizer with a 1-bit output Y accepts a 1-bit input X. Y becomes 1 only if the 1-0-1 pattern is seen at X. The circuit treats the incoming bit stream as overlapping sequences, i.e. the last bit of a previous sequence becomes the first bit of the next sequence. In effect, the circuit looks at the most recent three bits to check against the pattern, like below: X 0010101110100101011 Y 0000101000100001010
