The encoded inputs are {D, C, B, A} and the outputs are active low: O0 I like this! I can see in the circuit that you have already done some mental separation of the part that counts 0-15, and the part that turns the number into the "display values". circ file included in the repository. It is convenient to use an AND gate as the basic decoding element for the output because it produces a “HIGH” or logic “1” output only when all of its inputs are logic “1”. There are two output ports ( ‘ Data_out 1 ’ and ‘ Data_out 2 ’ ) for the register file. The Hexadecimal to Binary Encoder encoder usually consists of 16 inputs lines and 3 outputs lines.
