These routines model tropospheric radiowave propagation over variable terrain and calculates propagation loss vs. height and range. Propagation loss is displayed in dB contours on a height vs. range plot. TPEM is based on the split-step Fourier PE method and was originally developed from an early PE model called PEPC, written by Fred Tappert. Propagation loss over variable terrain is modeled by shifting the field an appropriate number of bin widths correspondc ing to the height of the ground. The field is determined using the smooth earth PE method.

It has been suggested1 that an appropriate figure of merit for a low probability of intercept and detection (LPI/D) waveform is the quantity “Range x Bandwidth / Joule”. That is, the further the range, the wider the bandwidth and the less amount of energy used to achieve these values, the more covert is the resultant communications system.

The SP486 and SP487 are low–power quad differential line drivers meeting RS-485 and RS-422 standards. The SP486 features a common driver enable control the SP487 provides independent driver enable controls for each pair of drivers. Both feature tri–state outputs and wide common–mode input range. Both are available in 16–pin plastic DIP and SOIC packages.

cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used to calculate a whole range of scientific functions including sin, cos, tan, arctan, arcsin, arccos, sinh, cosh, tanh, arctanh, log, exp, square root and even multiply and divide. the method dates back to volder [1959], and due to its versatility and compactness, it made possible the microcoding of the hp35 pocket scientific calculator in 1972. here is some code to illustrate the techniques. ive split the methods into three parts linear, circular and hyperbolic. in the hp35 microcode these would be unified into one function (for space reasons). because the linear mode can perform multiply and divide, you only need add/subtract and shift to complete the implementation. you can select in the code whether to do the multiples and divides also by cordic means. other multiplies and divides are all powers of 2 (these dont count). to eliminate these too, would involve ieee hackery.

Modern, large scale, display systems are migrating from traditional technologies such as incandescent, fluorescent and mechanical to sophisticated products based on LEDs. LED displays offer power savings and a superior visual experience in a range of products from programmable signage to large-scale video displays and commercial installations.

Enhanced version of the Serial Peripheral Interface available on Motorola s MC68HC11 family of CPUs.Enhancements include a wider supported operating frequency range, 4deep read and write fifos, and programmable transfer count dependent interrupt generation. As with the SPI found in MC68HC11 processors the core features programmable clock phase [CPHA] and clock polarity [CPOL]. The core features an 8bit wishbone interface. Very simple, very small.
