DTFT And Fourier Transform

DTFT And Fourier Transform

DTFT And Fourier Transform. Consider a continuous-time signal x a (t), and a sequence x(n) obtained by sampling x a (t) with sampling period T:. x a (t) has a fourier transform, X a (f). x(n) has a DTFT, X(e j2 p ft ). In chapter 6, this relationship was asserted without proof:.
