Orthogonal and in-phase responses in linear feedback model

Published June 26, 2013 at 800 × 400 in Orthogonal and in-phase responses in linear feedback model

The system response to a linear feedback is a combination of in-phase and orthogonal components.

These can be shown to be a direct response to the input and the time deriviate of the input that have been low-pass filtered .
