In order to prevent distortion in the output signal after amplificatio

1.	In order to prevent distortion in the output signal after amplification, the input signal must be(a) Higher than the positive saturation level of the amplifier(b) Lower than the negative saturation level of the amplifier(c) Must lie with the negative and the positive saturation level of the amplifier(d) Both higher than the positive saturation level of the amplifier and lower than the negative saturation level of the amplifierI have been asked this question during an interview.My question is based upon Amplifiers topic in chapter Signals and Amplifiers of Electronic Devices & Circuits
Answer» The correct CHOICE is (c) Must lie with the negative and the positive saturation LEVEL of the amplifier The best I can explain: HIGHER than the positive saturation and LOWER than the negative saturation level of the amplifier are the desired characteristics in order to prevent DISTORTION.
