Abstract
An interpolation FIR filter uses a coefficient to generate an interpolation value of a first and second input value. The interpolation FIR filter has several arithmetic units, an adder, and a divider. The narithmetic unit outputs a partial product by selecting one of the first and second input values according to an nbit of the coefficient, and multiplying the selected input value by 2. The adder outputs a sum all the partial products and the first input value. The divider divides the sum by 2, wherein m is an amount of the arithmetic units.
