- A few decades ago, I found a digital circuit that squares a 4-bit input in an old textbook (perhaps 1970s or 1980s). (The figure below is not the original. It differs from the original in that it has been rotated 90 degrees. Also the original figure had an error in the circuit diagram that has been corrected in the figure below.) I do not have access to that textbook any more and I do not have additional details about the textbook. Have you seen this circuit before? If so, could you give me the name and author of the source? I am using this figure in my teaching and I would like to properly cite the source.
