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....
