Question

Using the function below, answer the following questions using matlab

function f = SquareWave(t,A,T)

%% Initialise loop variables

n = 1; % Index for current half-period cycle

f = zeros(size(t));

%% Loop through all values of t vector

for i = 1:length(t)

% Update cycle index and swap sign of A every half-period T/2

if t(i) > t(n)+T/2

n = i;

A = -1*A;

end

% Squarewave function evaluation.

f(i) = A;

end

Question 1

Using the function from above, plot a square wave having amplitude ?=1, period ?=2?, over the domain −?≤?≤?. The vector, ?, must be resolved to 0.1 units.

Use a black dotted line of width 2 when creating your plot.

Question 2

Write a function file that takes a domain vector t, a scalar amplitude A, a scalar period T and a scalar representing the number of Fourier series terms n as inputs, and outputs a vector F that evaluates the Fourier series solution.

function F = FourierSqWave(t,A,T,n)
