Problem declaring a signal.
5 views (last 30 days)
I am a beginner in MATLAB and I'm studying for a test in Signal Processing and don't know how to tackle this some parts of this problem: "Using Matlab, convolve the two discrete-time signals: x1=(1/3)*(δ[n−1]+δ[n]+δ[n+1]) and x2 given by signal2.mat. Store the convolution (x1∗x2) in the variable x."
signal2.mat only contain the variable n which is an interval from -10 to 10 with a step of 1 and x2 which contain 21 random values.
I don't know what delta represents in x1 and how to implement/declare it in MATLAB. Any help is appreciated! I know what to do after I've declared x1, so further help than that is not needed!

The "δ[n]" generally refers to the Dirac delta function. The following code will help you generate the required signal.
More information about the Dirac delta function can be found on its documentation page.
