Binary multiplier is a combinational logic circuit or digital device used for multiplying two binary numbers. Two numbers are more specifically known as multiplicand and multiplier and the result is known as a product. The multiplicand & multiplier can be of various bit size. The product's bit size depends on the bit size of the multiplicand & multiplier. The bit size of the product is equal to the sum of the bit size of multiplier & multiplicand. In this text book Basic and Advanced Binary Multipliers are described.
