1. The problem statement, all variables and given/known data "The graph shows the characteristics of four different voltage amplifiers (A-D). The input voltage to these amplifiers is limited to between + & - 600mV. If you cannot see it properly it also says "If the input voltage is as shown (see bottom graph), sketch the output voltage for amplifiers B and D." 2. Relevant equations Voltage gain = change in output voltage divided by change in input voltage. 3. The attempt at a solution To use B as an example. I've tried finding the voltage gain (rise over run or the formula above) to get 8.33. I then use that as the voltage gain and rearrange the above formula but alas it didn't work. If it helps, the book shows (for B) a peak voltage of 1.8v and a trough of 1.8v. Any help would be appreciated.
