WebNormally, negative feedback is applied around an amplifier with high open-loop gain, to reduce the gain of the complete circuit to a desired value. Definition [ edit] The definition of open-loop gain (at a fixed frequency) is where is the input voltage difference that is being amplified. (The dependence on frequency is not displayed here.) WebYou can compute the closed-loop transfer function H from r to y in at least two ways: Using the feedback command Using the formula To compute H using feedback, type H = feedback (G,K) H = s + 2 --------------- s^2 + 2.5 s + 7 Continuous-time transfer function.
