Unformatted text preview: MATLAB, DSP, Graphics Module No: CM0268 Laboratory Worksheet 4: MATLAB Basic Digital Signal Processing Prof. D. Marshall Aims and Objectives After working through this worksheet you should be familiar with: The basic function of the Nyquist Sampling Theorem The creation, display and audio output of basic waveforms in MATLAB. The construction of more complex waveforms from basic waveforms in MATLAB. Understand the Z-transform and derive the Z-transform of a func- tion analytically and using MATLAB Understand the Inverse of the Z-transform and derive this inverse analytically and using MATLAB. None of the work here is part of the assessed coursework for this module 1 MATLAB Basic Digital Signal Processing 1. Basic Waveform creation and display : Create respective sine, co- sine, square and sawtooth wave forms each at the frequencies of 220 Hz, 440 Hz, 880 Hz. (You may choose appropriate sample frequen- cies and duration). Display these waveforms in individual MATLAB figures....
