Suppose we pass an input signal with a 3V Vpp and 4V DC offset into a non-inverting amplifier with a gain of 2 and no reference voltage. Assume the power supply rails, VDD and VSS, are high and low enough, respectively, to output any voltage we need. What is the Vpp of the output signal from the amplifier? Enter a numerical value (in V) with 2 decimal places and DO NOT include units (e.g. 3.14). Grading comment: What voltage is the output signal from the amplifier centered at? Enter a numerical value (in V) with 2 decimal places and DO NOT include units (e.g. 3.14). Grading comment: Now, assume that we give our non-inverting amplifier a reference voltage of 4V (acting as a virtual ground). What is the Vpp of the output signal from the amplifier? Enter a numerical value (in V) with 2 decimal places and DO NOT include units (e.g. 3.14)
