### Explanation of question 20

In Fig. 21.6, RX represents a receiver obtaining a signal via two paths. The received signal will be

1. twice as strong
2. suffering from fading
3. zero
4. in the form of pulses

The answer is :- 2 The constantly changing conditions in the ionosphere will mean that the receiver will not always be receiving the two signals in phase with each other, therefore fading will occur.
