Wo data streams are coming serially to a system. these two streams are carefully observed and if considering any four bits from each stream, we observe that these two input streams are equal; the fsm gives a signal to an alarm system to start warning the user. overlapping conditions need to be considered.
hint 1. a similar problem is posted on canvas (comparator) but for the other fsm model.
hint 2. you need to use an xor gate for comparing the bits of two streams and use its output as another sequence in which you will need to detect "", overlapping.

you need to:
use mealy state diagram and then construct the state table and state-assigned table using binary encoding [you need to have only 4 states) for these two cases:
(a) using dffs
(b) using excitation tables and tffs.
