摘要
本文在CM09上设计了fe中值混合滤波器的快速流水线实现。Blter结构将线性平均子Blter与中值运算结合在一起，以一种非常有效的方式实现。该滤波器去除噪声，同时保持信号的尖锐边缘。集成电路c a n工作到SOME。它可以接收实时视频信号，包括未来的高清电视应用。窗口大小可调，从S到257个样品。
A video frequency bit-parallel CMOS FIR median hybrid filter
Abs t r ac t Fast pipelined implementat ion of t h e F E Median Hybr id filter has been designed on CM09. The Blter structure combines linear averaging subBltto a median opera t ion in a way that leads to a very efeeieet implementation. The fi l ter removes noise while preserving sharp edges in t h e signals. The integrated circuit c a n operate up to SOME. clock r a t e s and it is capable of 5ltving real time video aignals including future HDTV applications. The window size is adjustable from S to 257 samples.
