Since I am only concerned with single digits and not multiple digits I only care about 0 to 9 being displayed. Since 0000 BCD corresponds to decimal 0 on the display I am assuming that Excess BCD 0011 corresponds to decimal 0 on that same display.Ģ. I would like to create a logic circuit diagram for an Excess-3 to BCD decoder so I am left to create the table from scratch.ġ. Most truth tables on-line show truth values for BCD to Seven-Segment decoders. As a result I would like to know if my assumptions are in the right direction. I would like to know if I am on the right direction for my truth table for a Excess 3-BCD to Seven Segment decoder. Therefore the input range ranges from 0011 to 1100 in binary inclusive with the rest of the inputs being don't cares. I am currently trying to construct a circut for an Excess 3 BCD to 7 Segment decoder.
