Consider a digital system which has four inputs. Make a circuit for the system using minimum number of NAND gates only if it gives high output when more than or equal to two inputs are high and otherwise low. |

You need 7 gates. 6 with 2 inputs and 1 with 6 inputs. 6 input NAND is not in program library, but comon product is 6 input NAND gate ie 7430. Not used inputs are commected to H or connected with other input. |
