Thus, the lengths of JIS B series paper are √ 1.5 ≈ 1.22 times those of A-series paper. By comparison, the lengths of ISO B series paper are 4 √ 2 ≈ 1.19 times those of A-series paper. Any Bn paper (according to the ISO standard) can be defined as Bn = S × L, where (measuring in metres)
In electronics, faithful amplification is the amplification of a signal, particularly a weak one, by a triode or a transistor such that the signal changes in amplitude but not in shape. [ 1 ] [ 2 ] [ 3 ] In order to achieve this with a bipolar transistor , the transistor is biased .
