Instrumentation and Measurement
Measurement: Magnitude + Unit
Instrument: A device for measuring something
Specifically the variables around us or we are concerned
about
Instrumentation: The engineering process and knowledge of making
such devices

Electronic/Digital Instruments
We live in an ANALOG world
We process in digital terms
We display on digital devices..
We transmit using digital schemes
We store in digital space

Sensor
Something that converts a piece of information from one type of
energy to another type electrical energy in most cases.
Why convert?
To digitally process and store/display/transmit

About Instruments
They have to be very:
Precise
Accurate
Sensitive
Resolute > Have fine resolution
Less erroneous > Low or no error
