When a signal of large amplitude is input to a amplifier, the main
parameters which determine the performance of the amplifier are
frequency response and its thermal conditions. When the frequency
of a input signal of large amplitude increases, the operating current
and power consumption of the amplifier will increase with the
increases of input signal even the amplifier is without load, and
signal distortion will increase with the frequency's increase as well.
And results in amplifier becoming hot, performance degradating.
Therefore, it is necessary made some restrictions on the frequency
and amplitude of inputing signals.
