WebGood, if a signal does not satisfies Dirichlet condition, signal Fourier transform does not exists, Even we are intrested to find its transformation just multiply the signal by exp (-sigma*t), where “sigma” is a real constant, and find the Fourier transformation to the resultant signal. WebHow condition for existence of Fourier transform is valid? (3 answers) Closed 6 years ago. As I know, if an aperiodic continuous-time signal be absolutely integrable, i.e. ∫ − ∞ ∞ x ( t) d t < ∞ its Fourier transform is existed. Also, the Fourier transform of cos ( ω 0 t) is π ( δ ( ω − ω 0) + δ ( ω + ω 0)). kurt weller blindspot actor https://3princesses1frog.com
