A feedback loop where all outputs of a process are available as causal inputs to that process. Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. [1] The system can then be said to feed back into itself. The notion of cause-and-effect has to be handled ...
Feedback is a key part of many forms of communication. It can be used to mitigate processes that may undermine successful communication, such as external noise or errors in the phases of encoding and decoding.
Communication is commonly defined as the transmission of information.Its precise definition is disputed and there are disagreements about whether unintentional or failed transmissions are included and whether communication not only transmits meaning but also creates it.
Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
[1] [23] [12] Feedback means that the receiver responds by sending their own message back to the original sender. This makes the process more complicated since each participant acts both as sender and receiver. For many forms of communication, feedback is of vital importance, for example, to assess the effect of the communication on the audience.
Two-way communication involves feedback from the receiver to the sender. This allows the sender to know the message was received accurately by the receiver. One person is the sender, which means they send a message to another person via face to face, email, telephone, etc.
The communication skills required for successful communication are different for source and receiver. For the source, this includes the ability to express oneself or to encode the message in an accessible way. [8] Communication starts with a specific purpose and encoding skills are necessary to express this purpose in the form of a message.
Positive feedback is used in digital electronics to force voltages away from intermediate voltages into '0' and '1' states. On the other hand, thermal runaway is a type of positive feedback that can destroy semiconductor junctions. Positive feedback in chemical reactions can increase the rate of reactions, and in some cases can lead to explosions.
