Response to the following problem:
The op amp in the precision rectifier circuit of Figure A is ideal with output saturation levels of ±13 V.
Assume that when conducting the diode exhibits a constant voltage drop of 0.7 V. Find v-, vO, and vA for:
(a) vI =+1 V
(b) vI =+3 V
(c) vI =-1 V
(d) vI =-3 V
Also, find the average output voltage obtained when vI is a symmetrical square wave of 1-kHz frequency, 5-V amplitude, and zero average.
