Generally speaking, the semiconductor diode in the circuit from the ''switch'' effect, that is, the passage of alternating current, from the ''pass''''off'' effect; digital signal through, from the ''0 ''or ''1'' role . Major semiconductor transistor in the circuit from the amplification effect is that when added to the transistor between the emitter and the base when the input signal changes, between the base and collector signal is amplified. This is the semiconductor diode and transistor in the circuit''s basic role. If you still feel not quite understand, you can refer to some basic knowledge of the semiconductor book to see, the book has the schematic, it will help you understand this knowledge. Your learning in good spirits, I hope you understand!
