Obviously, from the perspective of speed resolution, the best form of y(ξ) is also the shock function δ(ξ), so the similarity of y(ξ) and δ(ξ) is also used to measure the inherent resolution of the signal
Obviously, from the point of view of speed resolution, the best form of y (ξ) is also the shock function of the ξ, so the similarity of y (ξ) and the "ξ) is also measured by the degree of sensitivity inherent in the signal."
Obviously, from the point of view of velocity resolution, the best form of Y (ξ) is also the impact function δ (ξ), so the similarity between Y (ξ) and δ (ξ) is also used to measure the inherent resolution of signals
