Question in digital logic design????

Question

it is requierd to do a 7segment driver to display an octal number on a 7 segment LED display..

and this function have 3 input and 4 output...

and i try to minimize the fuction as possible as i can but it still in the function 22 gates ....how can i reduce it more???

Answer 1

Your question is not clear.  It appears that you have an octal input on three lines that you want to display as a decimal digit on a 7-segment display.  The display driver has 4 inputs (BCD).  The range of the input is 0-7, the range of the LED decoder/driver is 0-9.  Just connect the three octal inputs to the lower order BCD inputs (  0 to 0, 1 to 1 and 2 to 2).  And set the highest order BCD input (4) to zero level.  The display will then show the octal number.

If this is not what you are asking, post your question in the "engineering" category of science and mathematics.
