For the area shown in the figure, write the limits of integration using both the vertical and horizontal cross-sections, then evaluate the integrals. . Find the Fourier expression of the following periodic function 3 -3-2x

Write the Fourier expression for the first six non-zero sinusoidal terms for the waveform shown in the figure. Write the simplified Fourier series expression substituted value of the angular frequency and sketch the frequency domain representation of the harmonics for the waveform.

Do if you only know please and thank you

Fourier theory states that any sinusoidal signal may be represented or analyzed as the sum of a fundamental sine wave at the signal frequency plus odd, even, or odd plus even nonharmonic sine waves of different phases and amplitudes. True False

I need help with part d and part e. Please show clearly how to solve those parts. Thank you.

2.47 The Fourier transform of a signal is shown in Figure P-2.47. Determine and sketch the Fourier transform of the signal x1 (1) = -x(1) +x(t) cos(3000rt) + 2x(t) cos (5000rt). 500 500 Figure P-2.47

In the following, write out the Fourier series for the following. You should do the integrals yourself (show the steps), rather than just asking a program for the result. A. A triangular wave: -p < x < 0, f(x) = 0 0 < x < p, f(x) = x B. A half-wave rectifier -p < x < 0, f(x) = 0, 0 < x < p, f(x) = sin x

i need help with part a , b , c  , e thanks

Hello. I keep getting confused on this problem as I am new to Fourier series. Could you help me to solve this probelm? Thank you for your time and help.

I need the answer as soon as possible
