题目内容
Most amplifiers can be classified in by their function. If the output signal is larger in voltage amplitude than the input signal, the amplifier is a (). If there is no voltage gain, but the output power is greater than the input power, the amplifier is a power amplifier.

In the common-emitter amplifier circuit, the base terminal of the transistor serves as the input, the collector is the output, and the () is common to both.
In a non-inverting amplifier circuit, if the op-amp has an open-loop gain of 200000, the input voltage Vin = 1.5 volts, the inverting input resistor R1=10 kilo-ohms，the feedback resistor R2=0 ohms, then the output voltage can be calculated by using the formula. The output voltage Vout = () volts.
