Experiment for frequency domain analysis using MATLAB app designer (II)

Abstract

The Final Year Project (FYP) is a compulsory component for all graduating engineering students in Nanyang Technological University. My FYP requires the use of MATLAB App Designer to come up with an app that performs 2 things: - Frequency Domain Analysis (FDA) of signals - Audio Filtering In FDA, the first 5 Fourier Series Coefficients (FSC) of a specified input signal will be calculated. Following which, Fourier Transform (FT) will be performed on that signal which plots the signal in the frequency domain. This allows us to observe both, the original signal in the time domain and the processed signal in the frequency domain side-by-side, and make comparisons between the two. Next, an audio filter app will be used to analyse and remove noise from audio signals. This will return a clear audio signal without background interference.
