# Grey Code in Digital Electronics

Grey Codes are unweighted codes i.e. these codes are not positionally weighted. In a weighted code, a fixed value or weight is assigned to each position with in a binary number. This is not the case with unweighted codes. Continue reading

# Excess-3 Code in Digital Electronics

Excess-3 equivalent of a decimal number is obtained by adding 3 and then converting it to a binary format. For instance to find excess-3 representation of decimal number 4, first 3 is added to 4 to get 7 and then binary equivalent of 7 i.e. 0111 forms the excess-3 equivalent Continue reading

# Binary Coded Decimal in Digital Electronics

Binary Coded Decimal (BCD) codes are also known as weighted codes. To find a BCD equivalent of a binary number, each bit is multiplied by the corresponding weight. Continue reading

# Half Subtractor in Digital Electronics

Half Subtractor is a combinational circuit that performs subtraction of two bits and has two inputs and two outputs. The two inputs denoted by A and B represents minuend and subtrahend. The two outputs are the difference “D” and the borrow bit “Bo”. Continue reading

# Full Adder in Digital Electronics

Full Adder is a combinational circuit that performs addition of three bits. It consists of three inputs and two ouputs. Two of the inputs denoted by A and B are augend and addend bits that are to be added, & third input denoted by Ci represents the carry bit from the previous lower significant position. The two O/Ps are the sum ‘S’ of A and B and the carry bit, denoted by Co. Continue reading

# Half Adder in Digital Electronics

Half Adder is a combinational circuit that performs addition of two bits. It has two inputs and two outputs. The two I/Ps are the two 1-bit numbers A and B designated as augend and addend bits. The two O/Ps are the sum ‘S’ of A and B and the carry bit, denoted by ‘C’. Continue reading
