2. Browse around Fourier transform for some goodies-Continuous Fourier transform might be of use too.
3. In fact, as in the continuous Fourier transform, there is no basis in the continuous wavelet transform.
4. :Sure it's useful . . " Real " signals are seldom composed of a couple of simple pure frequencies that lend themselves to the easy continuous Fourier transform.
5. The Poisson summation formula ( PSF ) is an equation that relates the Fourier series coefficients of the periodic summation of a function to values of the function's continuous Fourier transform.
6. It's difficult to find continuous fourier transform in a sentence. 用continuous fourier transform造句挺难的
