Using Couleur's Technique (BIDEC), a binary number (most significant bit, MSB) first is shifted and processed, such that the bcd equivalent is obtained when the last binary bit is clocked into the register.
The basic rule is: if a 4 or less is in a decade, shift with the next clock pulse; if 5 or greater (...)

you should be able to do the transformation by first doing a mapping. Use the truth tables and the graphical method for each output bit.
Many years ago there were commercial ICs for this. Try looking through an old TTL data book. They will have diagrams of the logic inside the chips. 74185 is one example.

I suppose you meant ADC's output!
Indeed it is not trivial, specifically when converting the 8-bit binary to 10-bit bcd!
But converting the 10-bit bcd to 7-segment is easy, using for example IC-4511 or 7447!
A Truth table is one way, perhaps on a PROM!

Say you are using 8 bits. Then a value can occupy a range from zero to 255.
Say zero represents 0V, and 255 represents 5V. Then you can use a simple proportion to translate any value to a voltage.
To model this in electrical terms, each analog voltage is derived by sending 5 volts through resistors of different values.
Similarly each bit is weig
