Given the waveform below with A=6. f(t) ☑ 0 1 2 3 t(s) (a) Determine if the waveform has dc, even, or odd symmetry. (b) Obtain the cosine/sine Fourier series representation. (c) Convert the representation to amplitude/phase format and plot the line spectra for the first five nonzero terms.

Please help find the fourier series coefficients x[k] for the three waveforms. Please use the intergration formula for x[k]. Also sketch the magnitude and phase spectra. Thank you

Do if you only know please and thank you

Obtain the complex in Figure.. 2.8 Fourier series for the waveform shown - x() 0 A 2n

Please help with this question about fourier series. Show your solution and how to find time period.

Please take your time and make sure the answer is correct, and show all work. Thank you!

FOURIER SERIES ( NEED ONLY HANDWRITTEN SOLUTION PLEASE OTHERWISE DOWNVOTE).

- Define Fourier Series. Discuss an application of Fourier series. - What is the difference between odd and even function? Explain with example. -Obtain the Fourier coefficients of first four harmonics of the following periodic function: Assume any value for A, T1 and T2. SO A A -T2 -T1 0 T1 T2

Ques. 5: Find the exponential Fourier series for a rectified sine wave.

Determine the coefficients for the pulse train having a duty cycle of 0.5 and amplitude of 1 V and period of 2 s. Find the amplitudes of the fundamental frequency and the following six harmonics, i.e., n = 1,2, ... 7. Sketch the pulse train as an even function, then determine the Fourier series expansion. Repeat the procedure with the pulse train sketched as an odd function. Duty Cycle, D = Pulse Width Period PW = 0.5 x 2 = 1 PW T
