Non-inverting circuit. The classic non-inverting Schmitt trigger can be turned into an inverting trigger by taking V out from the emitters instead of from a Q2 collector. In this configuration, the output voltage is equal to the dynamic threshold (the shared emitter voltage) and both the output levels stay away from the supply rails.
In psychology and cognitive science, a schema (pl.: schemata or schemas) describes a pattern of thought or behavior that organizes categories of information and the relationships among them. [ 1 ] [ 2 ] It can also be described as a mental structure of preconceived ideas, a framework representing some aspect of the world, or a system of ...
The comparator hypothesis arose primarily in response to so-called “cue competition” effects. If for example in classical conditioning, two conditioned stimuli A and B are presented with an unconditioned stimulus, one may find on test that the subject responds to A or to B or to both or not very much to either.
Schmitt trigger implemented by a non-inverting comparator. Another typical configuration of op amps is with positive feedback, which takes a fraction of the output signal back to the non-inverting input. An important application of positive feedback is the comparator with hysteresis, the Schmitt trigger.
Figure 1 - containment image schema. An image schema (both schemas and schemata are used as plural forms) is a recurring structure within our cognitive processes which establishes patterns of understanding and reasoning.
For example, an agent (such as a mouse in the figure) is exposed to a light (the first conditioned stimulus, CS1), together with food (the unconditioned stimulus, US). After repeated pairings of CS1 and US, the agent salivates when the light comes on (conditioned response, CR).
A lay reader might think this had something to do with digital type memory, in which case this might be a bit confusing!) I completely agree that a graph would speak a thousand words. The inverting/non-inverting is a minor issue that can be easily fixed up. I might have a go one of these days! Graham 11:58, 19 November 2005 (UTC)
For example, spaces are symmetric. The distance between two points is the same regardless of which point you start from. However, psychological similarity is not symmetric. For example, we often prefer to state similarity in one direction. For example, it feels more natural to say that 101 is like 100 than to say that 100 is like 101.
