In this paper the method of designing circuit using modern digital signal processing is introduced. A digital down conversion (DDC) in digital IF receiver is designed based on modern DSP technology. a digital down converter (DDC) is used to convert between IF and baseband. These systems implemented interpolators and decimators and low pass filters that remove undesirable spectral imaging and protect against aliasing. A modified CIC in DDC which is called as ISOP_CIC is designed.
