I am a beginner at electronics and I am trying to solve my first problems with diodes and opamps. I have to find and draw the output voltage uο related to the input voltage ui knowing that the voltage drop on the diodes is 0.7V when they conduct. It is also known that opamps are ideal so I guess that no currents flow in or out of the inputs and the difference between the inverting and non-inverting terminals can be considered to be zero.
However, I am bit confused with the diodes. How do I start solving a problem like this? Do I have to assume first that ui is positive and then that ui is negative? Any help is appreciated! Thanks in advance.
