Decoder A device used to convert data by reversing the effect of previous coding. Decryption A procedure applied to ciphertext to translate it into plaintext. Decryption Key The key in the cryptographic algorithm to translate the ciphertext to plaintext. DECT Digital Enhanced Cordless Telecommunications Deemphasis Reinstatement of a uniform baseband frequency response following demodulation. De-Emphasis The restoration of a pre-emphasized signal wave to its original form (see Pre-Emphasis). Deep Well GaAs Processing of Gallium Arsenide (GaAs) based III-V semiconductor material to create a quantum well, rib, or trench within the material for use as a waveguide suitable for optical transmission. Schematic GaAs-AIGaAs Rib Waveguide, with loss mechanisms indicated: (1) epilayer roughness, (2) substrate leakage, (3) rib sidewall roughness, and (4) defect and impurity absorption. Rib width W, and height h are shown. Courtesy of IEEE Journal of Quantum Electronics, Volume 27, Number 3, March 1991, “Low-Loss III-V Semiconductor Optical Waveguides”, Robert J. Deri and Eli Kapon Delay The elapsed time between the instant when user information is submitted to the network and when it is received by the user at the other end. Delay Distortion Distortion resulting from non-uniform speed of transmission of the various frequency components of a signal; i.e., the various frequency components of the signal have different times of travel (delay) between the input and the output of a circuit. Also known as Group Delay Distortion.
