| Dual channel curvature has the advantage of having increased fidelity due to concavity and convexity data each being independently contained within their own channel & thus both are able to use the full range available. | Dual channel curvature has the advantage of having increased fidelity due to concavity and convexity data each being independently contained within their own channel & thus both are able to use the full range available. | ||
