![]() They are most commonly used in electronic devices like digital clocks, timers and calculators to display numeric information. I feel that there is a more efficient way to implement this, since the truth table somehow exhibits a "pattern". Published J4 A Aniruddh Patel Author 7 Segment Display A seven-segment display (SSD) is a widely used electronic display device for displaying decimal numbers from 0 to 9. Which will then be fed to the two BCD decoders that is: \$0010\$ to BCD deocder 1 and \$1001\$ to BCD decoder 2 so that the two seven-segment displays would show 29. The minterms are derived from the truth table for example: Where \$d_i\$ represents the input to the two BCD decoders connected to the two seven-segment displays and \$ABCDE\$ are the 5-bit binary inputs that must be displayed by two seven-segment displays. combinations for digits 6 and 7 arenever applied. You are to assume that only octal digits 0 to 5 are applied to the inputs of the decoder, i.e. \\d_4=A^\prime BD+A^\prime BC+AB^\prime C^\prime +BCD\\d_5=A^\prime BC^\prime D^\prime +AB^\prime C^\prime D+ABCD^\prime\\d_6=A^\prime B^\prime C+A^\prime CD+AC^\prime D^\prime+ ABC^\prime\\d_7=A^\prime B^\prime D+B^\prime CD+A^\prime BCD^\prime+ AB^\prime C^\prime D^\prime+ ABC^\prime D\\d_8=E 'Using multisim,design an octal-to-7-segment common cathode decoderfor digits 0 to 5 using the least possible number of NAND gates only. ![]() Without using an Arduino and microcontrollers, is this the most efficient way to implement two seven-segment displays to show 2-digit numbers (0-30) with the help of BCD decoders? ![]()
