Increasing return loss corresponds to lower SWR. Return loss is a measure of how well devices or lines are matched. A match is good if the return loss is high. A high return loss is desirable and results in a lower insertion loss. From a certain perspective 'Return Loss' is a misnomer. The usual function of a transmission line is to convey ...
In computer graphics, a digital differential analyzer (DDA) is hardware or software used for interpolation of variables over an interval between start and end point. DDAs are used for rasterization of lines, triangles and polygons.
A digital differential analyzer (DDA), also sometimes called a digital integrating computer, [1] is a digital implementation of a differential analyzer. The integrators in a DDA are implemented as accumulators , with the numeric result converted back to a pulse rate by the overflow of the accumulator.
The Numerical Electromagnetics Code, or NEC, is a popular antenna modeling computer program for wire and surface antennas. It was originally written in FORTRAN during the 1970s by Gerald Burke and Andrew Poggio of the Lawrence Livermore National Laboratory. The code was made publicly available for general use and has subsequently been ...
Reindeer prefer the cold, snowy climates of the northern hemisphere winters. It is difficult for a reindeer to survive outside of the frigid air.
WAXAHACHIE – An Ellis County detention officer died Monday after an inmate assaulted him, the sheriff said Tuesday. Officer Isaiah Bias, 28, started working for the Ellis County Sheriff's Office ...
A popular example is displaced phase center antenna (DPCA), which is a form of data-independent STAP in the beamspace, pre-Doppler. [7] The goal is to perform beamforming such that the beam appears stationary as the airborne radar is in motion over discrete time periods so the clutter appears without Doppler. [ 2 ]
From January 2011 to December 2012, if you bought shares in companies when Anne M. Finucane joined the board, and sold them when she left, you would have a 37.9 percent return on your investment, compared to a 12.1 percent return from the S&P 500.
