This is the information in my Slide please make me important questions based on this,"$1.$ A Digital Systemtakes a set of discrete input information $($inputs$)$and discrete internal information $($system state$)$to generates a set of discrete output information $($outputs$).$ Hence, an important characteristic of digital systems is their ability to represent and manipulate discrete elements of information. $$ Example: Digital Counter $$ Topic $1-$Part $1$ Page $3$ Types of Digital Systems: No system state $=>$ Combinational Logic System Output $=$ Function$($Input$)$ With system state State updated at discrete times $=>$ Synchronous Sequential System $$ State updated at any time $=>$ Asynchronous Sequential System $$ System State $=$ Function $($State$,$ Input$)$ Output $=$ Function $($State$),$ or $$ Output $=$ Function $($State$,$ Input$)$ Topic $1-$Part $1$ Page $4$ But, what do we mean by discrete elements of information? Any set that is restricted to a finite number of elements contains discrete information. $$ Examples of discrete sets: The decimal digits $\{0,1,2,...,9\}$ The English alphabet $\{$A$,$ B$,...,$ Z$\}$ The $64$ squares of a chessboard $$ Discrete elements of information are represented in a digital system by physical quantities called signals. $$ Electrical signals such as voltages and currents are the most common. $$ Electronic devices called transistorspredominate in the circuits that implement and manipulate these signals. $$ The signals in most present$$day electronic digital systems use just two discrete values and are therefore said to be binary. $$ A binary digit, called a bit, has two values: $0$ and $1.$ A digital system can be defined as a system that manipulates discrete elements of information $$ represented internally in binary form."
