Sir, the D Flip Flop does not depend on Q(t) (Previous output) the characteristic equation is : Q(t+1)= D. It is a memory element I understand but how is it a sequential circuit ?
@@yogeshsachdeva9566 oh okay. At every positive clock edge D flip-flop sees what is the value of D, It does "store" (storing element)the value of D until the next positive edge but it does not fit in the definition of combinational circuits which is "it depends on prev and present inputs" To store a 0 or 1 you need to continuously provide a 0 or 1 at D ? then how is it depending on the previous output?
Nice explanation
🥰 thanks sir.
sir in K map how did you consider even invalid states to be in a group

When the clock level is 0 or 1 (apart from when it is at +ve edge) the output depends on the previous value, ie. Q(t) (no change)
