Convolution theorem 意味

WebTheorem 2 fn(x)∈C∞converges uniformly to f(x) for all x ∈ R. Thus, on a compact set any continuous function can be ap-proximated arbitrarily closely in the uniform norm by a smooth function. PROOF The smoothness of the approximations fn is an im-mediate consequence of Theorem 1. Since f(x)= f(x) ¡R ∞ −∞ϕn(t)dt ¢ = R ∞ −∞f(x ... WebThe definition of convolution is, (f ∗ g)(t) = Z t 0 f (τ) g(t − τ) dτ. Change the integration variable: ˆτ = t − τ, hence dτˆ = −dτ, (f ∗ g)(t) = Z 0 t f (t − τˆ) g(ˆτ)(−1) dτˆ (f ∗ g)(t) = Z t 0 …
