  Synopsis

  Manual analyses of biomedical signals has many limitations and very subjective. Therefore, computer analysis of these signals is essential since it can provide accurate diagnosis as well as quantitative measurement. Hence, this course presents methods of processing the biomedical signals. The course will discuss the fundamental and current approach of biomedical signal processing. Among biomedical signal processing topics covered in this course are: Fourier analysis, Fourier transform, data acquisition, digital filter design and discrete Fourier transform. Furthermore, few current approaches on biomedical signal processing techniques were also introduced: instantaneous energy and frequency, short-time Fourier transform wavelet transform and time-frequency analysis
