After i finished doing all the truth tables and drawing the logic diagram, i decided to simulate it first before getting into any hardware stuff. Now, after i found every thing i need, i used Multisim and started connecting the outputs of 74ls93n to drive 4 LEDs instead 74ls93j 7-Segmentjust to test it first, and ran my design. Oct 11, 2.
