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. |
| A. | Both Statement I and Statement II are individually true and Statement II is the correct explanation of Statement I |
| B. | Both Statement I and Statement II are individually true but Statement II is not the correct explanation of Statement I |
