Design a decoder that able to drive 7 segment LED output as shown in Figure 1. The decoder has four bit inputs where the MSB (w) is the selector to select either Version A (MSB = '0') or B(MSB= '1') output. Another three bit number (xyz) indicating one of the eight directions (as shown below). The ouput for the 7 segment LED must follow the sequence of "abcdefg" where ' a ' is the MSB. A logic 1 (bold line) on line g, for example, lights segment g
