Webquently, h ∈C1(R). Repeating this we conclude that if f ∈Ck then h ∈Ck. Because of (2) f(k)∗g =g∗ f(k), so we can repeat this reasoning to show that g∗ f(k) ∈ Cℓ. Thus f ∗g ∈ Ck+ℓ. Note that although g might not be zero outside a bounded set, because f is zero outside a bounded set, the integration in g∗ f(k) is only over WebWe present an implementation of the overlap-and-save method, a method for the convolution of very long signals with short response functions, which is tailored to GPUs. We have implemented several FFT algorithms (using the CUDA programming language), which exploit GPU shared memory, allowing for GPU accelerated convolution.
