A decoder is a combinational circuit that converts binary information from n input lines to a maximum of 2" output lines. The input to the decoder is a BCD code and the outputs of the systems are the seven segments a, b, c, d, e, f, and g. For further information and pin connections, consult the specification sheet for decoder and 7-segment units. First design a combinational circuit which would simulate the decoder function for only the segment "a", of the display. This can be done in the following steps: a) Write down the truth table with 4 inputs and 7 outputs (Table 2) b) For only the output "a", obtain a minimum logic function. Realize this function using NAND gates and inverters only. For example if decimal 9 is to be displayed a, b, c, d, f, g must be 0 and the others must be 1 (For common anode type display units), if decimal 5 is to be displayed then a, f, g, c, d must be 0 and the others must be 1. c) Connect the output "a" of your circuit to appropriate input of 7- segment display unit. By applying BCD codes verify the displayed decimal digits for that segment for "a" of the display. d) Replace your circuit by a decoder IC 7447 for all of the seven segments. Observe the display and record the segments that will light up for invalid inputs sequence. e) Comment on the design if you don't want to see any digit for invalid input sequence. 27
