DISPLACEMENT CURRENTThe current that appears to flow through a capacitor [2]. |
DISTILLED WATERWater that has been purified through a process of evaporation and condensation [18]. |
DISTORTIONAny unwanted change between an input signal and output signal [6] [8]. |
DISTRIBUTED CONSTANTSThe constants of inductance, capacitance, and resistance in a transmission line. They are spread along the entire length of the line and cannot be distinguished separately [10]. |
DISTRIBUTIVE LAWIn Boolean algebra the law which states that if a group of terms connected by like operators contains the same variable, the variable may be removed from the terms and associated with them by the appropriate sign of operation (for example, A(B + C) = AB + AC) [13]. |
DOMAIN THEORYA theory of magnetism based upon the electron-spin principle. Spinning electrons have a magnetic field. If more electrons spin in one direction than another, the atom is magnetized [1]. |
DOMINANT MODEThe easiest mode to produce in a waveguide, and the most efficient mode in terms of energy transfer [11]. |
DONORAn impurity that can make a semiconductor material an N-type by donating extra "free" electrons to the conduction band [7]. |
DONOR IMPURITYSee PENTAVALENT IMPURITY [7]. |
DOORKNOB TUBEAn electron tube that is similar to the acorn tube but larger. The doorknob tube is designed to operate, at high power, in the uhf frequencies [6]. |
