Question:

Given below are two statements:

Statement I: There is a need to translate the original low frequency base band signal into high radio frequency before transmission
Statement II: To transmit a signal an antenna is required. As frequency increases size of antenna decreases.

In the light of the above statements, choose the most appropriate answer from the options given below.

Options:

Both Statement I and Statement II are correct

Both statement I and Statement II are incorrect

Statement I is correct but Statement II is incorrect

Statement I is incorrect but Statement II is correct

Correct Answer:

Both Statement I and Statement II are correct

Explanation:

The correct answer is Option (1) → Both Statement I and Statement II are correct

To transmit a signal effective, over long distance, the base band signal (low frequency) is often translated to a higher band frequency (RF).

To transmit a signal, an antenna is indeed required. The size of antenna is inversely proportional to the frequency of the signal.
