Yes I agree @Tanisha.

Generally we are using min and max term in digitial circuit like that the term will be 0 to 1 or others like that one is min and second one is max then the transister will be linear region and it also oprate in satutration region which help us the switch will be on and off.

Yes, I agree with this answer because the saturation and cut off mode are the most available for this question.

The transistor is always work in digital as a switch on/off or close/open and 0/1 is similar as 0V(low) and 5V(high)so, saturation and cutoff regions is the answer for digital function.
Although transistor is work in the active region because it has a biased voltage 5V/15V so ip is forward biased and op is reversed biased when ip is apply >0.8V op is 5V(high) and ip is <0.7V op is 0.4V(low).

In saturation region transistor acts as closed switch and in cut off region it acts as open switch. In digital circuits o/p can be 0 or 1. So when in saturation region means closed switch it gives output 1 and in cut off region means open switch it gives o/p 0.

Saturation mens input voltage is max and out is minimum so it can consider as zero and in cutoff region input is zer hence max output. So can consider as 1.

Digital circuits operate 0 or 1 in binary form. So saturation and cut off regions can operate the circuit.

Generally Digital circuits require swithcing elements and that's why tarnsistors whenever used in digital circuits, always are operated in saturation (ON) and cut-off (OFF) mode.

Priya is right. I totally agree with her. Good.

Digital circuits operates only in two modes ie saturation & cut off because it contains binary format 0 & 1 where it operates.
