Comparative Analysis of Serial Type and Parallel Type Seven-segment Numeric Display Decoding Circuit

Comparative analysis has been made of the serial type seven segment numeric display decoding circuit reflected in the result of the latest patent and existing parallel type sevensegment numeric display decoding circuit being in great use in terms of the decoding principle, decoding efficiency, loss of effectiveness, decoding circuit and some other aspects; and the derived conclusion is as follows: the two types of decoding circuits have different characteristics, different scopes of application and different advantages and disadvantages; and they form the relationship of mutual supplementation instead of that of mutual substitution
