In the theory of computation, a Mealy machine is a finite-state machine whose output values are determined both by its current state and the current inputs. (This is in contrast to a Moore machine , whose output values are determined solely by its current state.)

Derive flip how to draw round glasses In the same way that gates are the building blocks of combinatorial circuits, latches and flip-flops are the building blocks of sequential circuits. While gates had to be built directly from transistors, latches can be built from gates, and flip-flops can be built from latches.

## How To Draw State Diagram In Sequential Circuits

The combinational circuit does not use any memory. Hence the previous state of input does not have any effect on the present state of the circuit. But sequential circuit has memory so output can vary based on input. This type of circuits uses previous input, output, clock and a memory element. Flip
