If G j omega represents the Fourier Transform of a signal gt

If G (j omega) represents the Fourier Transform of a signal g(t) which is real ever symmetric in time, then G (j omega) is Select one: real imaginary complex real and non negative

Solution

for a real signal FT is complex conjugate even symmetric

and for even symmetric signal FT is real

for both real and evensymmetric the FT is real
