BCD-to-Excess-3 Code Converter for manual design • A serially-transmitted BCD (8421 code) word is to be converted into an Excess-3 code B in transmitted in sequence, LSB first • An Excess-3 code word is obtained by adding 3 to the decimal value and taking the binary equivalent. Excess-3 code is self-complementing Decimal 8-4-2-1 Excess-3 ...

This paper presents four different designs for a binary to BCD converter using two different concepts with each concept implemented using 90nm hybrid PTL/CMOS and 90nm CMOS technology. The power consumption of all four designs were evaluated on Tanner EDA tool 13.0. The power consumption was calculated for all the four designs at 100Mhz and
DATA FORMAT CONVERTER
ABSTRACT The Data Format Converter accepts nine-bit parallel binary data at a 5-kilohertz rate, combines the data with time readings, and records them on a one-half inch 7 track computer-compatible binary tape. The converter is a part of pulse position modulation (PPM) telemetry system, designed by the Sounding Rocket Instru- mentation Section .of Goddard Space Flight Center, which is used

The binary-coded decimal scheme described in this article is the most common encoding, but there are many others. The method here can be referred to as Simple Binary-Coded Decimal (SBCD) or BCD 8421. In the headers to the table, the '8 4 2 1' indicates the four bit weights; note that in the 5th column two of the weights are negative.

3. Example 1: MEALY machine design – BCD to Excess-3 code converter In this example, we’ll design a serial converter that converts a binary coded decimal (BCD) digit to an excess-3-coded decimal digit. Excess-3 binary-coded decimal (XS-3) code, also called biased representation or Excess-N, is a complementary BCD code and numeral system.

Write down the truth table of the converter. Binary Coded Decimal (BCD) is a way to store the decimal numbers in binary form. The number representation requires 4 bits to store every decimal digit (from 0 to 9). Since there are 10 different combinations of BCD, we need at least a 4-bit Gray Code to create sufficient number of these combinations.

The binary representation of the decimal number 843 is 11010010112. The BCD code representation of the decimal number 843 is 1000 0100 0011. The BCD code representation consists of the coded representations of the individual digits 8, 4, and 3. Referring to our chart or recalling the base2 representation for each - digit, you obtain 1000 0100 0011.
