ECE 3337 HW 5 _______________________ ______________ Due April 29 Tuesday 10am 2003 Name (Last, First) Student No Use this sheet as cover sheet 1. Consider a square wave of amplitude 1 from t = -1 sec to t = 1 sec. (a) Find the Fourier sine-cosine series, when the square wave repeats with a periodicity of 4 sec (the period from –2 sec to 2 sec). Plot the coefficients from n=0 to n=5. (b) Repeat the problem, but shorten the square pulse to half the duration (i.e. from - 0.5 sec to 0.5 sec) and increase the amplitude to twice as large.

Unformatted text preview: (c) Repeat problem (a), but change the periodicity to 8 sec (the period from –4 sec to 2sec). (d) Repeat problem (a), but change to a Fourier exponential series. 2. Text 3-10 3. Find the Fourier transform for the square pulse in 1(a). Plot the spectrum (the magnitude). What is the relationship of the spectrum in 1(d) to the current spectrum.
