Can a diode be used to amplifyt4 apnf :pv: ia/8j9ofn0d 0ik anvq3tx) n of +ho0ho9- signal? Explain. {yes|no}
A. yes
B. no
参考答案: B
本题详细解析:
No, a diode cannot be used to amplify a signal. A dio mr wm8/xm8*io a/on+sde does let current flow through it in one direction easily (forward biased) and it does not let current flow through it in the other direction (reversed bias), but there is no way to connect a source of power to use it to amplify a signalais/wrnom x m* mo8/+8 (which is how a transistor amplifies a signal).
