Question Paper

1. Draw a block diagram representation of a generalized measurement system. Identify the various elements and describe the functions performed by each element /component.

Define the dynamic response of a system and distinguish between steady state response and transient response.

Sketch and explain the response of a first order system when subjected to ramp input signal. Indicate thereon the transient error, steady state error and the time lag.

Differentiate between 'accuracy' and 'precision'.

A circuit was tuned for resonance by eight different operators and the values of the resonant frequency in kHz were recorded as
412,428,423,415,426,411,423 and 416.

Calculate

Arithmetic mean

Average deviation

Standard deviation

Variance

What is meant by 'standardization' of a potentiometer? How is a dc potentiometer standardized

With relevant diagrams explain how the dc potentiometer can be used to calibrate dc ammeter and dc voltmeter.

Draw the block diagram of a true r.m.s reading voltmeter and explain its operation.

What are its advantages and limitations?

What is an LVDT? Explain the principle of operation of an LVDT.

Describe a method of measuring the rotational speed of an electric machine. What are the merits and demerits of the method?

Draw the block diagram of a CRO and explain the functions of each block.

Make a comparison between PDM and PCM telemetering systems

8. Explain with the help of a neat circuit diagram the working of a digital frequency meter. Name the techniques used for the measurement of high frequency.

Explain the types of distortions which may occur in a signal.

Draw the block diagram of a wave analyser and explain how it work. Also mention its advantages and disadvantages.
