A BCD-to-seven-segment decoder is a combinational circuit thatconverts a decimal digit in BCD to an appropriate code for theselection of segments in a display indicator used for displayingthe decimal digit in a familiar form. The seven outputs of thedecoder ( a, b, c, d, e, f, g ) select the corresponding segmentsin the display.
Design the BCD-to-seven-segment decoder using a minimum number ofNAND gates for each segment.
Assume the 2 cases below in each of your designs:
a) The six invalid combinations should result in a blank display
b) Assume the six invalid combinations cannot occur
