Abstract

Anti-aliasing filter is used to remove the frequency components higher than Nyquist frequency so as to reduce alias error. It is very important for precise measurement and analysis of dynamic signal. The maximum useable frequency range of the dynamic signal measurement system is derived in this paper. The method for design and optimization of a switched capacitor filter based tunable anti-aliasing filter is discussed in detail. The test result shows that the filter can satisfy the strict system requirement through careful design and implementation, while the filter circuit is relative simple.
