This paper describes an adaptive filtering to reduce noise in the analog input circuits of microprocessor-based protection relay (digital relay) systems. Considering that digital relays tend to have multiple functions, it is important to raise signal to noise ratios (SNR) in analog input circuits to a level that will satisfy the requirements of these functions. We have realized a noise reduction method...
A bit-sliced rank order filter LSI for real-time two-dimensional processing of TV video signals has been developed, fabricated by 2 um CMOS standard cell technology. The LSI architecture, suitable for real-time and adaptive processing and enabling the input word length to be easily expanded, is presented.
