Ch. 2 Convolution C-T System Model Convolution Integral D-T System Model Convolution Sum Ch. 3: CT Fourier Signal Models Fourier Series Periodic Signals Fourier Transform (CTFT) Non-Periodic Signals New System Model New Signal Models Ch. 5: CT Fourier System Models Frequency Response Based on Fourier Transform New System Model Ch. 4: DT Fourier Signal Models DTFT (for Hand Analysis) DFT & FFT (for Computer Analysis) New Signal Model Powerful Analysis Tool Ch. 6 & 8: Laplace Models for CT Signals & Systems Transfer Function New System Model Ch. 7: Z Trans. Models for DT Signals & Systems Transfer Function New System Model Ch. 5: DT Fourier System Models Freq. Response for DT Based on DTFT New System Model Course Flow Diagram The arrows here show conceptual flow between ideas. Note the parallel structure between the pink blocks (C-T Freq. Analysis) and the blue blocks (D-T Freq. Analysis). 3/13 The m-file motor_speed.m is available for download from the course website. To run it all you need to do is: 1. Download it to a folder on your computer a. Make sure Matlabs current directory is the folder where you have put the m-file (change it if needed) 2. At the Matlab command line type: motor_speed 3. The m-file will run and create several figures Example: D-T Processing for Motor Speed 4/13 Suppose you have a motor whose shaft is connected to a sensor that...
