MATLAB question

Write MATLAB script(s) to plot the basic signals below in two subplots. The upper subplot should be a continuous waveform (don't do g) and the lower subplot should be a discrete plot. a) Sinusoidal waveform b) Exponential Waveform c) Damped Sinusoid d) Sinc function e) Step Function & Square Wave f) Triangle Wave g) Impulse Function Make sure there are enough points so that the upper plots look continuous, and fewer points for the lower subplots, so that points are distinguishable. Also, Write a/multiple function(s) to perform the various signal transformations. a)scaling b)translation c)reflection This should be a coded function. I.e. -> function signal_out-transform... click for more

MATLAB convolution simulation

Write and verify a computer program to perform the convolution of two discrete signals. [1] The convolution program should be written as an m-file able to handle two general discrete signals. The M-file will be ain function file format, it will take two inputs sin1, sin2, and return an output sout. sin1, sin2: can be row or column vectors of any length sout: will be a row vector (length is determined by input vectors) Ex: function sout=convolution(sin1,sin2) { %put your code here with comments } 2. Test with the following signals: (Plot all results -> use the stem command) Case 1: h(n)=1 for 1click for more

DSP analog filter problem

This problem is taken from the Textbook 'Digital Signal Processing using MatLab' by Ingle/Proakis. The below system (in the attached file) acts as an analog filter. The analog signal m(t) is passed through an analog to digital converter and m(k) is the resultant discrete or digital output in the form e^(jw). The discrete signal m(k) in the form e^(jw) is applied to the discrete filter h(k) with an impulse response of h (k) = (0.5) k u (k). This is in essence the transfer function of a LTI system. The transfer function is described. See attached file for full problem description.
