Mobile communication has become an important part of our daily lives for voice communication and data sharing and access over the Internet. Mobile communication is an open network, so maintaining the privacy and reliability of data has always been anxiety. The reliability of the data against channel noise can be achieved by various error correction codes. The purpose of the channel coding process is to reduce the effect of some disruptive elements that the information is influenced in the transmission phase as much as possible, which is to ensure that the data is delivered to the receiver with minimum error. For that purpose, we use filters, which can be an analog filter and digital filter. From the today scenario, Digital filters have many advantages, such as higher precision, higher stability. In this paper, the signal passes through various types of digital filters and finds their different response which describes the filter accuracy with respect to the input audio signal. MATLAB is the best software of numerical analysis, providing user-friendly coding commands. Through the MATLAB design part of filter done by some procedures and given the frequency characteristics curve, comparing the results.
