Sensor technology
A senor is a device that converts a physical phenomenon into an electrical signal. As such sensors represent part of the interface between the physical world and the world of electrical devices, such as computers. The other part of this interface is represented by actuators, which convert electrical signals into physical phenomena.
In recent years, enormous capability for information processing has been developed within the electronics industry. The availability of inexpensive microprocessors is having a …showed first 75 words of 441 total…

All sensors have finite response times to an instantaneous change in physical signal. In addition, many sensors have decay times, which would represent the time after a step change in physical signal for the sensor output to decay to its original value. The reciprocal of these times correspond to the upper and lower cutoff frequencies, respectively. The bandwidth of a sensor is the frequency range between these two frequencies.
