We can observe that the circular convolution is a superposition of the linear convolution shifted by 4 samples, i.e., 1 sample less than the linear convolution’s length. That is why the last sample is “eaten up”; it wraps around and is added to the initial 0 sample.

In combinatorial mathematics, a circular shift is the operation of rearranging the entries in a tuple, either by moving the final entry to the first position, while shifting all other entries to the next position, or by performing the inverse operation. A circular shift is a special kind of cyclic permutation, which in turn is a special kind of permutation. Formally, a circular shift is a permutation σ of the …

If K is an integer, then circshift shifts along the first dimension of A whose size does not equal 1. If K is a vector of integers, then each element of K indicates the shift amount in the corresponding dimension of A. Note city beach carindale opening hours
