I will just explain what a bit is. It's a binary digit. 0 is numerically zero, 1 is numerically one. If you want to add 1 and 1, in binary it overflows. the result is 0, and a carry out. As you understand, other arithmetic operations can be done on bits. They takes a fair bit of logic to implement. Binary is positional. That means that a 1 which is 4 places ...

Quibbling about the right meaning of "bit" aside, some advantages of the 2-of-7 biquinary representation are: Simpler circuits. In a quinary adder circuit, the output of each of the 5 output lines becomes just a 5-way OR of binary ANDs of input lines. To implement this with primitive logic building blocks such as resistor-transistor-logic (or its vacuum-...

From a modern chip design perspective, the design of bi-quinary adders is quite simple. The addend inputs are each composed of two 1-hot signals, and the sum output is two 1-hot signals as well. This is by the nature of bi-quinary, where the quinary part is 1-hot by definition and the binary part is a 2-bit signal that is 1-hot by convention, being either ...
