The conventional optical M-ary spread spectrum (M-ary/SS) system requires a correlator with all sequences and and maximum likelihood estimation as the demodulator. The correlator needs to be optimally ...
Abstract: This paper presents an absolute capacitive rotary encoder using a sample-and-hold demodulator (SHD) to reduce interference between sine and cosine channels. The capacitive encoder measures ...
