Question

Directions: It consists of two statements, one labelled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answers to these items using the codes given below:

Statement (I):

For radar tracking systems, signals are available in the form of pulse trains.

Statement (II):

The stability of a discrete-time system is decreased as the sampling period is shortened.

1. Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)
2. Both Statement (I) and Statement (II) are individually true but Statement (II) is not the correct explanation of Statement (I)
3. Statement (I) is true but Statement (II) is false
4. Statement (I) is false but Statement (II) is true

Answer 1

Correct Answer - Option 3 : Statement (I) is true but Statement (II) is false

A radar system uses a radio-frequency electromagnetic signal reflected from a target to determine information about that target. The most common type of radar signal consists of a repetitive train of short-duration pulses.

Therefore, statement I is true

The stability of a discrete-time system is increased as the sampling period is shortened.

Therefore, statement II is false
