Design an 8421 BCD to 2421 BCD converter circuit. The truthtable as follows:

Note that input combinations of 1010 to 1111 can be treated as"don't cares".

Generate the logic equations for each of the 4 outputbits. For the actual circuitimplementation, you are restricted to using the 74LS small scalelogic integrated circuits from 74LS00 up to 74LS32. This gives youa mix of logic gates that implement AND, OR, NAND, AND NOR logicfunctions with up to 4 inputs. Refer to the device data sheets thatcan be found on the Texas Instruments web sitewww.ti.com.

NOTE! This circuit can beimplemented using five ICs or less. You are not required toimplement a minimal design but the more logic gates you have inyour design, the more actual wiring will be needed which increasedthe probability of a wiring error. You will need to generate acircuiit schematic detailing all of your logic gate connections aswell as a list of the integrated circuits required.
