DIFFERENCE FREQUENCYSee BEAT FREQUENCY [18]. |
DIFFERENCE OF POTENTIALA voltage between two points [6]. |
DIFFERENTIAL AMPLIFIERA circuit that amplifies the difference between two input signals [8]. |
DIFFRACTIONThe bending of waves (as light or RF) when the waves are met with some form of obstruction [10]. |
DIFFUSION(1) The scattering of reflected light waves from an object, such as white paper [10]. (2) Controlled application of impurity atoms to a semiconductor substrate [14]. |
DIGITA symbol that represents one of the nonnegative integers smaller than the radix. For example, in decimal notation a digit is one of the characters from 0 through 9 [13]. |
DIGITAL COMPUTER(1) A computer in which discrete representation of data is used. (2) A computer that operates on discrete data by performing arithmetic and logic processes on these data [13]. |
DIODEAn electron tube containing two electrodes: a cathode and a plate [6]. (2) A two element, solid-state device made of either germanium or silicon; it is primarily used as a switching device [7] [13]. |
DIODE DETECTORA demodulator that uses one or more diodes to provide a rectified output with an average value that is proportional to the original modulation [12] [18]. |
DIPOLEA common type of half-wave antenna made from a straight piece of wire cut in half. Each half operates at a quarter wavelength of the output [10]. |
