Please draw the circuit

Make an extended seven-segment display that must show the numbers from 0 to 9 and the letters: A and b Draw the logical functions circuit that control segments for 0-3 using a decoder and the logic OR gates (a single decoder must be shared by the logic gates OR); for 5 - an 8-to-1 and 4 multi, for 4, 6-OR, AND, NOT logic gates in minimum numbers (minimal SOP). Design the truth table of the display. Simplify using SOP the logic functions controlling segments 4 and 6 with Karnaugh's method
