Before we start implementing we first need to check if it is common anode or common cathode. If it is common anode then 3rd pin in both top and bottom are VCC. But if it is we should connect 3rd pin in both top and bottom to ground. From here we can get minimized expressions for a, b, c, d, e, f, g using K-MAP.

BCD to 7 Segment LED Display Decoder Circuit Diagram and Working

We can follow similar procedure for the rest. A 7 segment decoder can show maximum 9 in decimal format It can also show A to F in case of hexadecimal. Using 3 bits the maximum number we can represent is 7. So in order to show 8, 9 on display you need 4 bits.

Just make K Map for all the inputs of the 7 segment decoder using the table. Now do it for all other columns.

Using 4 bits combinations possible which is 16 from 0 to You are commenting using your WordPress. You are commenting using your Twitter account. You are commenting using your Facebook account.

Otherwise A, B, C, D can also be inputs and MSB, LSB will be opposite. Now input D, C, B, A as in which case D is MSB and A is LSB.

Now input the table given above in the table tab. We can just input values by single or double clicks. Logisim Diagram For Decoder Table: Twitter Pocket Facebook Tumblr Google Email Print Reddit LinkedIn Pinterest.
