In this lecture, we are going to learn about the 4 bit binary to bcd converter in very detail with a truth table, K-map, and circuit realization of Binary to BCD converter. Before starting to know about this conversion we will see steps to be followed for this conversion.
4 Bit Binary To BCD Converter
Steps to Be followed:
We will convert a 4-bit binary to 5-bit BCD words. TH procedure to be followed is as follows:
Step 1: Write the truth table showing the relation between binary as input and BCD as output.
Step 2: For each BCD output, write a K-map.
Step 3: From the k-map obtain a simplified expression for each BCD output in terms of binary inputs.
Step 4: Realize the code converter using the basic gates.
Binary To BCD Converter Truth Table
- The below table shows the truth table for Binary to BCD.
- B3 B2 B1 B0 is the four-bit binary word with B3 acting as MSB.
- D4 D3 D2 D1 D0 is the five BCD output.
