Is it possible to evaluate the Fourier Transform of the Four

Is it possible to evaluate the Fourier Transform of the Fourier Transform of a real valued signal?

If not, explain why not, if so, find out the F { F { x(t) } }.

Solution

No it is not possible to evaluate the Fourier Transform of the Fourier Transform of a real valued signal because when we calculate the Fourier Transform of the real valued signal it is converted into frequency domain and we calculate Fourier Transform of the time domain signal and not frequency domain signal . Thus it is not possible to evaluate the Fourier Transform of the Fourier Transform of a real valued signal.

Also Fourier Transform integral canot be calculated .
