You will first need to design a multiplexer to convert each 7-segment LCD pattern to a BCD. Truth table with 7 inputs (a b c d e f g) and 4 outputs (A B C D) from the following truth table:

You will first need to design a multiplexer to convert each 7-segment

TRUTH TABLE SN54/74LS48 5 INPUTS OUTPUTS DECIMALRBI FUNCTION NOTES: (1) BI/RBO is wired-AND logieserving as blanking input (BI) and/or ripple-blanking output (RBO). The blanking out (BI) must be open or held at a HIGH level when output functions 0 through 15 are desired, and ripple-blanking input (RBlI) must be open or at a HIGH level if blanking of a decimal 0 is not desired. X=input may be HIGH 8 (2) When a LOW level is applied to the blanking input (forced condition) all segment outputs go to a LOWlevel, regardless of the state of any other input condition. (3) When ripple-blanking input (RBI) and inputs A, B, C, and D are at LOW level, with the lamp test input at HIGH level, all segment outputs go to a HIGH level and the ripple-blanking output (RB0) goes to a LOW level (response condition). (4) When the blanking input/ripple-blanking output (BI/RBO) is open or held at a HIGH level, and a LOW level is applied to lamp-test input, H H HIL all segment outputs go to a LOW level 4 TRUTH TABLE SN54/74LS48 5 INPUTS OUTPUTS DECIMALRBI FUNCTION NOTES: (1) BI/RBO is wired-AND logieserving as blanking input (BI) and/or ripple-blanking output (RBO).
