For the below problem, please compute the fourier coefficients. In addition, please detemine if the waveform has a$)$ DC component b$)$ If the quadrature form of the series has only cosine terms, only sine terms, or both. c$)$ whether the series has only odd numbered harmonics, only even numbered harmonics, or both d$)$ the spectral rolloff rate in decibels$/$octave$.$ e$)$ the lowest frequency $($other than DC$)$ that does not have an amplitude of zero. Assume waveform continue indefinitely with the pattern shown $2-19$ See the figure that follows.
