This signal conditioning may include amplification, filtering, sensor excitation, and input configuration.
Baird did this by making a better photoelectric cell and making the signal conditioning better.
Various other examples of signal conditioning might be bridge completion, providing current or voltage excitation to the sensor, isolation, linearization.
Most optocouplers leave the signal conditioning at the input and/or output to the designer, which is not always the easiest to implement.
Moving the signal routing and signal conditioning to a single location in the test system has the following advantages:
The PowerLab system is essentially a peripheral device designed to perform various functions needed for data acquisition, signal conditioning and pre-processing.
Cooperation with the customer produces application-specific sensor systems that combined macro sensors and electronic signal conditioning at module level.
In addition to providing the required excitation, power supplies may also incorporate additional signal conditioning, such as gain, filtering, buffering, and overload indication.
An onboard signal conditioning assembly and fiber optic towed decoys.
A modular front-end, called a daughterboard, is used for analog operations such as up/down-conversion, filtering, and other signal conditioning.
