  1. I have a weird feeling that these questions are unanswerable: Compare linar to logarithmic For this question I wrote that a logarithm is an exponent to which a standard number is raised to produce a given number. Then I explained the base of natural and common logs. Then to explain linear I described it as something that is uniform, or the same. Why are amplifier gains commonly given in decibels? State 2 reasons I explained that it was becuase of the dBm and dBk standards, and the fact that you can show loss easily.; Coupling caps must have a reactance of less than 1/10th of the input impedance of the amplifier. Would this be for the uppermost, average, or lowest frequency? Why? For this I wrote that it should be for all, shouldnt it be? Why does the common emitter amp have a 180 phase shift? I had zero clue why this happens. My teacher claims that he told us this, but I have NO evidence of it in my notes. Any help here?
