Signal Analysis of Real Time Signals

Abstract

Removal of noise is very important branch in Digital Signal Processing. This paper addresses the analysis of real time signals to finally remove noise from the signals. In the proposed technique these signals are analyzed by comparing the results in Spectrum Analyzer and MATLAB. This is performed by evaluating the FFTs first and Hanning window is applied to it. Similar process is done in MATLAB. By analyzing these real time signals we can say that the results in Spectrum Analyzer are almost same with the results in MATLAB.
