Use properties (Text Table 3.1) to find the exponential Fourier series coefficients, , k a (including ) of the following periodic waveforms. Note that we derived a very general formula for square pulse trains. Feel free to use this formula and results from one part of the problems below in any other part. a (a)(15) (b)(15) ) ( t x 1 2 3 4 5 6 7 8 -1-2 1 -8 -7 -6 -5 -4 -3 t t ) ( t x 2 1...
