This is a MATLAB question. How can I do the question with a loop?

Q3: [25pts) A Fourier series is an infinite series representation of a periodic signal (i.e., function) in terms of sines and cosines at a fundamental frequency (matching the period of the waveform) and multiples of that frequency. For example, consider a square wave signal of period L given below. 1 1/2 L 30/2 24 This function can be represented by the Fourier series as: f(x) = n 1 sin i=1,3,5,... Assume that 0
