modulated optical device
• LCDs are available to display arbitrary images or fixed images with low
information content such as preset words, digits.

8. • A Current Sensor is an important device in power
calculation and management applications. It measures
the current through a device or a circuit and generates an
appropriate signal that is proportional to current
measured. Usually, the output signal is an analog
voltage.
