Direction: The following item consists of two statements, one labelled as ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer using the codes given below:Statement (I): An analog system has at its output stage a PMMC indicating instrument, while a digital meter output stage has an LCD/LED display device.Statement (II): Since the analog system is continuous in time, display device can respond to it if the signal frequency is low, while digital system being a discrete one, it does not required change and can be latched at the value of measurement.
In measurement systems, which of the following are undesirable static characteristics?
In a measurement system, which of the following static characteristics are desirable?
Directions: Each item consists of two statements, one labeled as ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer using the code given below:Statement (I): The smallest change of input detectable at the output is called the resolution of a transducer.Statement (II): A high resolution means high accuracy.
Meter A has a range of 0 – 100 V and a multiplier resistance of 28 kΩ and an internal resistance of 2 kΩ. It’s sensitivity is:
