Fourier Transform of Sinusoids 1/2 -ω 0 1/2 j(1/2) ω -ω 0 ω -j(1/2)

Fourier Transform of Sinusoids 1/2 -ω 0 1/2 j(1/2) ω -ω 0 ω -j(1/2) Notes l l A real value for the coefficients in the frequency domain means that the starting point for rotation is on the real axis An Imaginary value for the coefficients in the frequency domain means that the starting point for rotation is on the imaginary axis © Tallal Elshabrawy 22
