Agilent EEsof EDA Applications: Digital Modulation Simulations

Designers who wish to analyze circuits in which digital modulation is used have available a full range of simulations in a single design environment: Advanced Design System (ADS).

Among these analyses are adjacent-channel power (ACPR), bit-error ratio (BER), power-added efficiency (PAE), constellation and trajectory diagrams, and vesitigal side band (VSB) measurements.

Additional design support is provided by a growing number of examples and training classes, and by Agilent EEsof EDA technical support.
