The required 7-segmrnt decoder should have 3-inputs (which are the bits of the binary number desired to be designed, call them A,B,C), and 7 outputs (the 7 segments of the display unit which are a, b, c, d, e, f & g). 8. gf a b t la Ob d Dp e d8c Dp The 7-segment to be used is of common anode type. Consequently, any segment will be ON if its input is Low, meaning that for displaying 0 the segments inputs (a,b,c,d,e,f.g) should be (0000001), or g will be OFF while all the others are ON. 1- Make a table explaining the inputs and the corresponding outputs for the 6 combinations input (000.101), assuming the other two combinations as don't care. 2- Find the output as a function of the inputs (A,B,C) using K-map to minimize the expressions 3- Show your design using 2-input, and 3-input NAND gates, and inverter.
