Q. An amplifier using an opamp with slew rate SR=1v/μsec has a gain of 40dB. if this amplifier has to faithfully amplify sinusoidal signals from dc to 20 KHz without introducing any slew-rate induced distortion, then the input signal level must not exceed

• (A) 795 mV
• (B) 395 mV
• (C) 795 mV
• (D) 39.5 mV
