makes it bigger! (or sometimes smaller, or sometimes the same, but with lower output impedance)
amplifier will strengthen da small input signal n amplifies it
An amplifier amplifies the small input signal to a high signal without changing its freqency.
Small signal amplifier is needed because it is used for amplifying input signals having low frequency or amplitude.
As the name suggests, it amplifies a small signal. It ususally has a very high input impedance, to avoid affecting the source signal.
Small signal amplifiers are generally referred to as "Voltage" amplifiers as they convert a small input voltage into a much larger output voltage.

Amplifiers are electronic device that responds to a small input signal (voltage, current, or power) and delivers a larger output signal.
An amplifier is both an input and output device. An amplifier, as its name suggests, amplifies a signal, meaning that it makes it stronger. An amplifier takes something as input, like maybe a sound signal, and its output is a more powerful (or louder) version of the same signal.
Answer is GAIN
A; An amplifier will have no effect on the input frequency however its output may not follow the input frequency at the hi end due to the amplifier limitations
slew rate is the ability of an amplifier to reproduce amplified version of the input signal in terms of frequency and phase. The input signal amplitude change is fast. But the amplifier will take some time to give response to the changes in input signal. i.e. how fast the amplifier tracks the input signal is the slew rate. For an amplifier the slew rate should be high in order to avoid signal distortion. The rate of change of the output voltage of an amplifier for the given input signal change is called the slew rate.
