Circuit indicates the operation of switching elements that are associated with the activation or inhibition of operations by certain circuits . For example, the gearshift is connected to the transmission as a manually operated shifting element in vehicles . The word circuit is used in the following technical terms:
- in neuroinformatics and neurophysiology as a neural circuit
- in electrical engineering as an integrated circuit
- in theoretical computer science as a Boolean circuit
The term circuit is used as an independent term in neurophysiology , for example . (a) It is not used in DIN standards for electrical engineering . In the International Electrotechnical Dictionary , too , the word circuit only appears completely hidden (and not in one of the relevant chapters). Common expressions instead of circuit are circuit , control loop, or circuit . The word component “circle” indicates a self-contained system in the sense of feedback . (b) According to neuron theory , nerve cells or groups of nerve cells can take over the function of switching elements.
To separate the circuit from the control circuit
The German word "switch" means - especially in its combination with "switch and walten" in etymological terms "freely proceed with something". This is followed by the much more common electrotechnical use of “switch”. This "free procedure" includes the inclusion of a person acting at his own discretion in the circuit. The inclusion of free acting people in the system of the circuit has been called bionics . This seeks to solve technical problems based on the model of biological functions. But also the diverse support provided by technology for people, for example in the field of prostheses or biotechnology, is part of this science. Bionics has gained scientific importance for verifying theories through computer simulation methods , see for example the concept of synapse weights .
In contrast, the control loop is to be understood as an automatically running event in the sense of a closed, purely technical "cycle". Although this can be influenced by the manipulated variables , the system in principle remains stable even without such influence.
