Document Summary
Transducer: a device that converts variations of one quantity into those of another (same or different form) Sensor: a device that detects a change in a physical stimulus and turns it into a signal that can be measured or recorded. Actuator: a device that produces an observable output. Thermometer: (thermal) thermocouple op amp led display (radiant) Signal is an electronic representation or analogy (either current or voltage) of the original parameter. A function is used to represent the original parameter value e. g. , frequency used to represent intensity of light. A parallel digital signal represents the original parameter signal e. g. , an 8-bit wide encoding of a temperature. Relate to performance, given a steady-state input condition. Describe behavior between the time that the input value changes and the time at which the steady-state condition is achieved. Range: defines the limits between which the input can vary. In general, a wide range implies low resolution and low accuracy.
