ECE 561 – Digital Communications Systems MATLAB Assignment #2 Turn in all commands, models, results, and output graphs for the problems below. 1. Create a Simulink model consisting of a Sine Wave (from the Signal Processing Blockset Sources), a Time Scope and a Spectrum Scope (both from the Signal Processing Blockset Sinks). Display the output of the Sine Wave source on both the Time and Spectrum Scopes. Set the Sine Wave to display a 1V amplitude, 1KHz sine wave with the sample mode set to Discrete. a. Set the sample time of the Sine Wave is set to 1/2200 (2.2 times the frequency). Set the Spectrum Scope to Buffer Input with a buffer size of 1024, buffer overlap of 0 and Boxcar Window type. Display the magnitude-squared of the spectrum (not in dB). Simulate the model so that four FFTs can be computed and averaged. Observe the waveform and spectrum of the signal. Print out and turn in the spectrum display and waveform display. Zoom in so that approximately two cycles of the waveform are displayed. b.
