Multispectral Remote Sensing.  Multispectral remote sensing is defined as the collection of reflected, emitted, or backscattered energy from an object or area of interest in. multiple bands of electromagnetic spectrum; while Hyperspectral remote. sensing involves data collection in hundreds of bands.
A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit.Resistors can also be used to provide a specific voltage for an active device such as a transistor.All other factors being equal, in a direct-current (DC) circuit, the current through a resistor is inversely proportional to its resistance, and directly proportional to the voltage across it.esistors can also be used to provide a specific voltage for an active device such as a transistor.

From Wikipedia, the free encyclopedia. In electronics, a differentiator is a circuit that is designed such that the output of the circuit is approximately directly proportional to the rate of change (the time derivative) of the input. An active differentiator includes some form of amplifier.
