The two bcd digits together with the input carry are first added in the top 4 bit binary adder to produce the binary sum. The four bit parallel adder is a very common logic circuit. Bcd to 7 segment logic diagram pspice 7 segment display digital integrated circuits march 7th 2018 its operating principle is to input a four bit bcd binary coded decimal value and energize the proper output lines to form the corresponding decimal digit on the 7 segment led display the bcd inputs are designated a b c and d in order from least.
