We introduce the closed form relations for the design of fast IIR filters for interpolation, decimation, and QMF banks with perfect magnitude reconstruction. The design is based on the third-order half-band IIR filters and the fifth-order non minimum-phase optimal FIR filters.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.

First of all, an overview of the NRD guide technology progress is presented. It indicates that the hybrid planar/NRD-guide (HP/NRDG) technology provides a straightforward assembly of MMIC circuits with NRD-guide. To begin with, a simple fabrication technique for NRD-guide is described, which allows the fabrication of complex NRD circuits in a single step. Then, a new magic tee junction based on HP/NRDG technology is presented with measured results. New mode suppressor topologies compatible with the HP/NRDG technology are discussed for spurious waveguide modes, the LSE/sub 10/ mode and also the LSM/sub 10/ mode. Finally a discussion is made on different design possibilities of HP/NRDG power amplifier topologies. The present overview of some of our ongoing research work on the HP/NRDG technology suggests that the realization of a low-cost millimeter-wave transceiver is possible.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.

The design of a 32-bit bus transceiver is efficient when either capacitive load/coupling between bus lines causes transitions or signal delays on such lines with respect to the fault-free case, or when permanent faults (stuck at zero/one) on bus lines exist. Transient errors are detected by self-testing checking hardware, while permanent faults are sensed by boundary scan logic. The transceiver features high-speed online detection and can be implemented using custom and semi-custom VLSI ICs, very deep submicron technology, as well as low-cost FPGAs.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.
