prime number dedector

 Design a digital circuit that turns on LED when 1, 2, 3, 5, 7, 11, 13 causes on a 4 bit data bus.                Here we are going to design a digital circuit that glows an LED when prime numbers till 16 is “ON” on a 4 bit data bus. To design such circuit, the apparatus required are: APPARATUS: 1.  IC 7408, 7432, 7402. 2.  4 10K Ohm resistor. 3. ...
