Question

Although digital signals which have partially degraded cannot be fully recovered, computers still operate using these, due to the fact that transistors can only represent two states. True/False

Answer 1

False.

Step-by-step explanation:

Transistors don't represent 2 states they represent 4 states or modes of operation which are as following:-

1. Saturation:- In this mode the transistor acts like a short circuit.There is free flow of current.
2. Cut-off:- The transistor acts like open circuit.
3. Active:-In this mode the current flowing through collector and emitter is proportional to current flowing in the Base.
4. Reverse-Active:-It is like the active mode but the current flows in the reverse direction.Flow of current is from emitter to collector.
