A final design of the manchester decoder and encoder was completed in record time. The encoder is of course, the simpler part ( or so they say). However, it turned out that when loopback was applied to the encoder decoder combination the source of malfunction in the initial iteration was traced to the so called easy part, the encoder. So designer beware, the decoder only seems more difficult. It is the encoder that will get the designer in trouble.There are few “nitty-gritties” that have to be addressed.
