And/or Seven Segment Display

This circuit uses four inputs all leading into and gates to or gates displaying to each segment of a seven segment display.

The Seven segment display is most frequently used the digital display in digital systems. Since the outputs from various chips are going to the seven segment display as a 4-bit BCD (Binary Coded Decimal), the out puts are not meant to be a directly installed to the seven segment display. For that, we use a display decoder to convert BCD code into seven segment code.
