(b) Design a non-inverting amplifier to provide a closed loop gain of 60. Draw the schematic and briefly explain its operation. (c) You have built the circuit from the previous question (A1 (b)) and are testing its output for an AC input signal with 10 mV peak amplitude. The output signal measured on the oscilloscope has peak amplitude of approximately 420 mV. Assuming your measurements are correct, is this what you expected? Provide a possible justification for this result.
