2. Give the abbreviation form for RNA, DNA? :
RNA –Ribo Nucleic Acid DNA—De- Oxy Nucleic Acid

3. What are resting and action potential, bio electric potential? :
The membrane potential caused by the different concentration of ions is called resting potential. It is caused by very rapid change of membrane permeability to sodium ions followed by recovery period.

The positive potential of the cell membrane during excitation is called action potential. Certain systems of the body generate their own monitoring signals conveying useful information about the functions they represent. Such signals are bio electric potentials and are related to nerve conduction, brain activity, heart beat etc.

4. What is meant by measurement? :
Measurement is an act or the result of comparison between the quantity and a predefined standard.

5. Mention the basic requirements of measurement :
The standard used for comparison purpose must be accurately defined and should be commonly accepted. The apparatus used and the method adopted must be provable.

6. What are the 2 methods for measurement? :
1.Direct method and
2. Indirect method.

7. Explain the function of measurement system :
The measurement system consists of a transuding element which converts the quantity to be measured in an analogous form the analogous signal is then processed by some intermediate means and is then fed to the end device which presents the results of the measurement.

8. Define Instrument :
Instrument is defined as a device for determining the value or magnitude of a quantity or variable.

9. List the types of instruments? :
The 3 types of instruments are
**Mechanical Instruments
**Electrical Instruments and
**Electronic Instruments.

10. Classify instruments :
**Absolute Instruments
**Secondary Instruments

11. What are the 2 modes of operation of secondary Instruments? :
**Analog mode and
**Digital mode

12. What are analog devices? :
Signals that vary in a continuous fashion and take on infinity of values in any range are called analog signals. The devices that produce these signals are called analog devices

13. What are digital devices? :
Signals that vary in discrete steps and thus take on only finite different values in a given range are called digital signals. The devices that produces these signals are called digital devices.

14. Mention the functions performed by the measurement system :
**Indicating function
**Recording function
**Controlling function.

15. Give the applications of measurement systems :
The instruments and measurement systems are sued for
**Monitoring of processes and operations.
**Control of process and operations.
**Experimental engineering analysis.

16. List the functional elements of the measurement systems :
**Primary sensing element.
**Variable conversion element and
**Data processing element.

17. What is signal conditioning? :
The performing of non-linear processes like modulation, detection, sampling, filtering, chopping and clipping etc. on the signal to bring it to desired form is called signal conditioning.

18. What is data transmission element? :
When the elements of an instrument are actually physically separated, it becomes necessary to transmit data from one to another. The element that performs this function is called a data transmission element.

19. Give the function of the variable manipulation element :
The function of the variable manipulation element is to manipulate the signal presented to it preserving the original nature of the signal.

20. What are the characteristics of the measurement system? :
**Static characteristics
**Dynamic characteristics
