Q: Was feedback present in the ordinary pendulum ..? ¶
A: Yes, between its position and its momentum—a 'feedback' that, from the practical point of view, is somewhat mystical.
Q: Was feedback already current in the 1920s with the introduction of the regenerative circuit? ¶
A: Yes.
Q: Is feedback said to be positive? ¶
A: Yes.
Q: Is feedback to be considered present only when there is an actual wire or nerve to represent it? ¶
A: Yes, and then the theory becomes chaotic and riddled with irrelevancies.
Q: Is feedback the video equivalent of acoustic feedback? ¶
A: Yes.
Q: Was feedback replaced by electronic engine management systems once small? ¶
A: Yes, and robust and powerful single-chip microcontrollers became affordable.
Q: Is feedback an also useful design principle for designing user interfaces? ¶
A: Yes.
Q: Is feedback extensively used in control theory? ¶
A: Yes, and using a variety of methods including state space , full state feedback , and so forth.
Q: Is feedback widespread in the design of electronic amplifiers? ¶
A: Yes, and oscillators, and stateful logic circuit elements such as flip-flops and counters.
Q: Is feedback also central to the operations of genes and gene regulatory networks? ¶
A: Yes.
Q: Is feedback often deliberately introduced to increase the stability and accuracy of a system by correcting or reducing the influence of unwanted changes? ¶
A: Yes.
Q: Is feedback defined in different ways within different disciplines? ¶
A: Yes.
Q: Is feedback used extensively in digital systems? ¶
A: Yes.
Q: Is feedback being employed and closed loop if feedback is being used? ¶
A: Yes.
