Digital Trainer Kit using Decimal to BCD Encoder Practical (IC 74147) /Electronics/Trainer Kit

Decimal to BCD Encoder experiment using a Digital Trainer Kit and verify its operation.

📌 A Decimal to BCD Encoder is a combinational circuit that converts decimal input (0–9) into its Binary Coded Decimal (BCD) output.

🧠 Theory:
An encoder converts multiple input lines into a smaller number of output lines.
The IC 74147 is a priority encoder that converts decimal inputs (D0–D9) into 4-bit BCD output.
