Handbook of Diodes, Rectifiers, Thyristors and Transistors [antikvár]

1. List of Symbols Quantity Symbols 1. Instantaneous values of varying quantities are identified with lower-case symbols, e. g. i. V, p. 2. Peak values of periodic functions, pulse amplitudes, various average values and DC parameters (DC voltage. DC current) are designated with upper-case symbols, e. g. I. V, P. Subscripts for Quantity Symbols 1. Resulting quantities measured from a given zero level are denoted with applying uppercase symbols in their subscripts, e. g. ic. Vbe- 2. Small letter subscripts refer to average values of varying quantities, e. g. ic, Ic. Vbe. Vbe 3. Peak, average as well as r.m.s. values use the following subscripts: for peak values and amplitudes: M. m for r.m.s. values: eff, RMS for average values: AV, av 4. Examples of the application of the symbols. The figure represents a transistor collector current consisting of a direct current and a varying component. Subscripts for quantity symbols of diodes IX
