It is speatial types of 4(quard bit) bit representation of a number. Such as if a number in decimal 12 it is represented by BCD as 00010010.7 segment display have so many application. Though now a day digital display LCD, LED used widely but for low price application 7 segment display widely used. For students project ( MCU related project) it is widely used. BCD to seven segment decoder are designed in verilog HDL.
