The circuit is designed to map 4-bit binary inputs to the segments of a seven-segment display. The truth table and logic for each segment are implemented using basic logic gates (AND, OR, NOT). If you ...

Overall, a Gray counter circuit is an efficient and effective way to count in a specific sequence, with minimal complexity and more straightforward decoding compared to a traditional binary counter. A ...

This study presents the design and development of a virtual laboratory for the Logic design course. A novel implementation of a BCD to seven-segment decoder is shown, which allows student to connect ...

In engineering circles, this circuit is better known as a 7447 BCD to seven-segment decoder/driver, but just using a single chip has little pedagogical value.

Logic 0 will turn on a segment, and logic 1 will turn it off. A lookup table in the MCU code is used to generate the desired display. U4 can be two sections of a 74HC14 or one 74LVC2G14/NC7WZ14.
