That depends on both the input signal and the type of amplifier the transistor is used in.
pulse of positive voltage is not indicate to zero
AM wave is produced by applying the modulating voltage to the base of a transistor amplifier.
The voltage gain (Av) of a transistor amplifier can be calculated using the formula ( Av = \frac{V_{out}}{V_{in}} ). In this case, the output voltage is 5 V rms and the input voltage is 250 mV rms (which is 0.25 V). Therefore, the voltage gain is ( Av = \frac{5}{0.25} = 20 ). This means the amplifier has a voltage gain of 20.
A simple, 1 transistor single stage amplifier can be made using several resistors to bias a NPN or PNP transistor into its' linear operating region. With this done, a small voltage signal applied to the input of the amplifier will have the voltage amplified at the output in a linear fashion. I'm not sure what your question is; if this does not answer it let me know.
A power amplifier may also boost voltage; in audio equipment, power amplifiers often have a dial on the front that is used to control the input voltage gain. A simple power amplifier is composed of a single transistor; this type of configuration cannot provide voltage amplification as well. A voltage amplifier stage is needed. So the above example of an audio power amplifier is actually a voltage amplifier stage, followed by one or more power amplifier stages.

If inceres the base voltage of transistor them it may be burn . The base volt may be 0.8v to 1.8 If it use as a amplifier
the out put voltage will be much grater then the input voltage.
