WEBK-Map for XS-3 Bit X 3. The K-map simplification for the XS-3 bit X 3 is depicted in the figure below −. This K-map gives the following Boolean expression, X3 = B3 + B2 B1 + B2 B0 X 3 = B 3 + B 2 B 1 + B 2 B 0. The logic circuit diagram of the BCD to XS-3 converter is shown in the following figure −.

WEBAug 26, 2018 · A BCD (Binary Coded Decimal) can be converted into Excess-3 by. Taking the 3 rd value as a start and continue up to 9. After the 9, make it as a don’t care. A don’t care is a condition which can be used in K-mapping technique.
WEBInputs: a BCD input, A,B,C,D with A as the most significant bit and D as the least significant bit. Outputs: an Excess-3 output W,X,Y,Z that corresponds to the BCD input. Internal operation – circuit to do the conversion in combinational logic.

WEBAug 27, 2018 · Excess-3 to BCD converter: The excess-3 input starts only from 2, so the don’t care conditions are added for BCD output (o,1,2). The Binary Coded Decimal has only 10 i.e (3 to 12) and the remaining are don’t care conditions. K-map for B3:
WEB1. Add 0 to the MSB to get 4-bit binary number. From the truth table in Table (1), we see the conversion of 4-bit binary numbers to its corresponding Excess-3 code. B0 – B3 represents the BCD number where B0 is the LSB and B3 is the MSB.
