This circuit inputs a 4-digit binary number and outputs a decimal digit 0 to 9 using a 7-segment LED display. If a number larger than 9 is input, then the display is blank.
Thanks to Mateusz Baran for contributing this circuit. -- Credits: Mr. Paul Falstad.

|Those that take 4 inputs and 3 inputs? How is that possible can a NAND gate take 3 inputs and AND gate 4 inputs?

|@JOhn : It can be possible and it can be implemented using P-MOS and N-MOS together in a circuit i.e. what is called C-MOS. There we can implement Three Terminal NAND GATE . It is a universal gate which is used commonly so can proceed further.|

|What does the top row of gates do? Don't understand.|
