【實用工具app】EVM Calculator|最夯免費app-綠色工廠好玩App

This tool is designed for the EVM (Error Vector Magnitude) budget analysis in the communication and RF (Radio Frequency) system engineering, where the RF and digital impairments of different sub-systems are often modelled and qualified as EVM in % during top-level design and analysis stage. The system engineer often evaluates the trade-offs between cascaded sub-systems to reach an feasible balance between cost, design effort and performance. This tool models 4 cascaded sub-systems with EVM effect modelled as additive noises. A simple EVM and SNR conversion calculator is also included. This will be a useful tool for RF and wireless system engineers and students.
