An input signal is blurred by a set of functions to obtain a blurred multichannel signal.
A numeric vector of length n of the signal of interest
An n by m matrix of blur functions to be applied to the signal of interest.
Applies the convolution operator to the signal of interest with each column of G to create a multichannel blurred signal. This operation is done in the Fourier domain using the base R fft transforms.
