Q.  What is the use of notch filters in Loran-C receivers?

a. Reduce interference from other frequencies
b. Reduce interference from other stations
c. Reduce interference from sky waves
d. Reduce atmospheric noise


ANSWER: See Answer
 
Loran-C signal reception can be impaired by interference from other signal broadcast on slightly different frequencies. To avoid degradation of S/N associated with these interfering sources, Loran -C sets are equipped with notch filters.
