COMPONENTS

× Bandpass Filter

MWJ5216 The Ultra-Q model 50368M is designed to eliminate cellular and paging interference in multiple address systems, but can also be extended to any application requiring a programmable bandpass filter, including VHF, UHF, cellular, PCS and the original MAS bands. Ultra-Q can operate from narrow band voice grade to CDMA types of modulation. Elimination of interfering frequencies relatively close to the system operating frequency is made possible via the high Q of 28,000 offered by Ultra-Q. It will not degrade the desired signal and is programmable with any laptop or PC. The unit is only 3' high and fits neatly into a standard 19' rack (custom options are also available). Weight: 3 lb.

SOFTWARE

× Filter Design Software

MWJ5252 Version 4.0 of FilterExpress digital filter design software has added a companion simulator called FilterSim. The Windows-based tools provide electronic and communications systems designers with an extremely rapid means of developing and evaluating DSP-based filters of almost any kind, including processor efficient multi-rate designs. The professional quality software is highly intuitive to use. FilterExpress allows designers to create most common filter configurations in minutes. Designs may then be simulated with FilterSim using built-in signal generator facilities or a user's own test data. The numeric precision of the tools is user-programmable to allow filter designs to be optimized for the target DSP hardware. When satisfied with the results, the filter's coefficients may be saved in ASCII format for import into a user's DSP development software. Free downloads area available from www.systolix.dsp.com
