Comment on "Serial Binary-to-Decimal and Decimal-to-Binary Conversion"

In the above article¹Rhyne describes a technique for serial binary to BCD (and BCD to binary) conversion using a single clock pulse per bit, as opposed to the two clock per bit method described earlier by Couleur [1]. Although Rhyne may be correct that his method has not been published in the official "scientific engineering" literature, it turns out that this same method has been published several times previously in the "trade" literature [2], [3]. One difference is that previous articles have implemented the technique with "D" flip-flops, as opposed to the "J-K" flip-flops used in the Rhyne article.
