Answer Posted / govind vijayakumar
Just put a SIPO (Serial In Paralle Out)Network at the
output, followed by a gate network.
4 parallel outputs from the SIPO are taken and the signal
lines whose output is supposed to be one are fed to a 3
input and gate. The 0 output is fed to a not gate and the
output of both the gates are anded together. If this
sequence comes then output will be one, otherwise 0.
