MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The output of combinational circuit at any instant of time, depends only on the levels present at input terminals. The combinational circuit do not use any memory. The previous state of input does not have any effect on the present state of the circuit.

Detailed explanation-2: -A combinational circuit is a digital circuit type where the output is only a pure function of the present input. The sequential circuit is a digital circuit type whose output relies not just on the current values of the input signals it has but it depends on the past sequence of inputs as well.

Detailed explanation-3: -A stable state of a sequential circuit is described as previous, present, or next. The present state is the present logic output of the circuit. The previous state is the logic output of the circuit before the present state. The next state is the logic output of the circuit after the present state.

Detailed explanation-4: -A sequential circuit is a type of digital logic circuit whose output not only relies on the current input but also depends on the previous output. Hence, a sequential circuit is basically a set of combinational circuits and memory elements connected in a feedback path.
