Abstract: Noise detection and reduction has become a primary concern in the fields where high speed and reliable communication is the essential criterion. It is therefore necessary to develop and build certain real time components, which can be made to work under the conditions of real-time environment where reliability and speed should be very high. In this field of Real-Time Digital Signal Processing numerous processors have been made by various companies like Texas Instrumentation, Motorola, Intel, etc. These devices offer an agreeable solution for this application. A comparable study has been made between some of the kits namely TMS320C5402 made by Texas Instrumentation. For the purpose of analysis a fundamental Active Noise filter design has been used as a test program and results are obtained from real time working conditions.
