`
`"A family’s responses to crisis or to a
`new situation mirror those of a child.
`That is to say, the way a small child
`deals with a new challenge (for
`instance, learning to walk) has certain
`predictable stages: regression, anxiety,
`mastery, new energy, growth, and
`,feedbaek for f utare achievement.
`These stages can also be seen in adults
`coping with new life events, whether
`positive or negative."

`b. that part of the output signal fed back into the input
`2. the return of part of the sound output by a loudspeaker to the

`feedback definition
`
`American Heritage
`
`A process in which a system regulates itself by monitoring its own
`output. That is, it "Feeds back" part of its output to itself. Feedback
`is used to control machines; a heating system, For example, uses a
`[:.h..e.r..m...o.s..t.a..t to monitor and adjust its output. Feedback is also used
`by the human brain to control various muscles and joints.
`
`Note : By extension, "Feedback" is any response or information
`about the result of a process.
`
`Note : Feedback is usually a Feature of automation.

`
`feedback definition
`electronics
`Part of a system output presented at its input. Feedback may be
`unintended. When used as a design feature, the output is usually
`transformed by passive components which attenuate it in some
`manner; the result is then presented at the system input.
`Feedback is positive or negative, depending on the sign with which a
`positive change in the original input reappears after transformation.
`Negative feedback was invented by Black to stabilise vacuum
`tube amplifiers. The behaviour becomes largely a function of the
`feedback transformation and only minimally a function of factors
`such as transistor gain which are imperfectly known.
`Positive feedback can lead to instability; it finds wide application in
`the construction of oscillators.
`Feedback can be used to control a system, as in f__e_e__d__b__a_c__k___c_o__n__tF_O_J.
