New RF/Analog Library Simplifies IEEE 802.11 DSSS and BFSK System Simulation

LANIX, Inc. introduced in March a powerful new version of its graphical filter design package available as part of the SystemView by ELANIX dynamic system simulator. This new filter design package gives designers the ability to design linear systems as Elliptic Filters and Sin t/t Filters and incorporate these filter types into their system simulation. These filters are essential for designers of modern digital and analog communication systems. In addition to the new filter types available, ELANIX has added a new graphical interface that allows users to synthesize filters by dragging poles and zeros in a Root Locus plot representation of the system. When designing modern digital communications systems designers require a complete range of linear systems. Elliptical filters, for example, are often used in the design of satellite communication systems. ELANIX’s new Elliptical filter models provide full support for both analog and digital (DSP bit-true IIR) Elliptic filters. Designers may specify the number of poles, passband ripple, and stopband attenuation. They may also select lowpass, bandpass, or highpass filter types. Sin t/t filters are of interest to engineers designing digital comm systems. ELANIX’s new Sin t/t filter models are zero inter-symbol interference filters.
