      divided into groups of 4 or 5. Solution. The proof is by strong induction. Let P(n) be the proposition that a class with n students can be divided into teams of 4 or 5. Base case. We prove that P(n) is true for n = 12, 13, 14, and 15 by showing how to break classes of these sizes into groups of 4 or 5 students: 12 = 4+4+4 13 = 4+4+5 14 = 4+5+5 ...

There are three basic architectures which may be used to produce log amps: the basic diode log amp, the successive detection log amp, and the "true log amp" which is based on cascaded semi- limiting amplifiers. The voltage across a silicon diode is proportional to the logarithm of the current through it.
