This simulation shows the working of a BCD to 7-segment display decoder. The four input lines (A, B, C, D) provide binary-coded decimal signals, which are then decoded into corresponding outputs to drive the seven segments (hex) of the display. Depending on the input combination, the decoder activates specific segments to form numeric digits on the display. The waveforms above represent the changing logic levels of the inputs, and the 7-segment display shows the according hex number for the give
