Abstract

This invention is a circuit for detecting a framing pattern consisting of a pseudo random shift register sequence. This circuit utilizes an extremely long framing pattern without either a large amount of memory or the need to receive a large number of bits in order to recognize the framing pattern. The use of lengthy framing patterns minimizes the chance of false framing caused by patterns in bit positions other than the framing bit position. In addition, the incoming data stream may be connected directly to the shift register mechanism.
