Anybody tell me what is the significance of cut off region?

But transistor is mostly used as an amplifier in active region of it.

Digital circuits used for switching purpose thats why transistor works only in saturation and cutoff region.

For switching purpose transistor are used in saturation and cutoff. Whereas for amplification purpose transistor are used in active region.

As far I think that Digital circuit require switching element (ON&OFF) , that why transistor whenever used in digital circuit always operate in saturation (ON) & cut off (off) in region. Basically the digital circuits operate only binary digits (i.e. 0 and 1) , when ever this is operates in bjt saturation region (the switch is on) , &the cut off region (the switch is off).

In digital circuit We works with either HIGH or LOW, so when transistor is in saturation (Vce i.e. max) it is on high voltage, and low voltage when it is in Cutoff (0V).

Should be in saturation and cut of region.

Digital circuits always operates in two modes that is 1 & 0, and we can also say that though its a circuit so the transistor can be act as a switch, and switch always obtained in saturation and in cut-off modes. Active mode is used only for amplification factor.

Digital circuit requre swiching element (ON&OFF) , that why transistor whenever used in digital circuit always operate in saturation (ON) & cut off (off) in region.

Basically the digital circuits operate only binory digits (i.e 0 and 1) , when ever this is opearates in bjt saturation region (the swith is on) , &the cut off region (the switch is off).
