Perbedaan Rangkaian Kombinasional dan Sekuensial :
- Rangkaian kombinasional terdiri dari gerbang logika yang memiliki output yang selalu tergantung pada kombinasi input yang ada.Rangkaian kombinasional melakukan operasi yang dapat ditentukan secara logika dengan memakai sebuah fungsi boolean.
- Rangkaian sekuensial merupakan rangkaian logika yang keadaan outputnya tergantung pada keadaan input-inputnya juga tergantung pada keadaan output sebelumnya. Rangkaian ini juga didefenisikan sebagai rangkaian logika yang outputnya tergantung waktu.
