The number of columns in a state table for a sequential circuit with m…

Here we all know that, for every of the M flip-flops, we've to put in writing this because the next state of flip-flop.

So, for M=1, we should always have 2 entries, one for this state and one of the consequent states.

So, for M flip-flops, there'll be 2M columns for flip-flop state data.

If there's one input, then there'll be one column.

so for N input, we should always have N columns.

so, total columns in state table = 2M + N
