If F1 and F2 are the lower and upper cutoff frequencies of a band pass

1.	If F1 and F2 are the lower and upper cutoff frequencies of a band pass signal, then what is the condition to be satisfied to call such a band pass signal as narrow band signal?(a) (F1-F2)>\(\frac{F_1+F_2}{2}\)(factor of 3 or less)(b) (F1-F2)⋙\(\frac{F_1+F_2}{2}\)(factor of 10 or more)(c) (F1-F2)
Answer» Right OPTION is (d) (F1-F2)⋘\(\frac{F_1+F_2}{2}\)(factor of 10 or more) The BEST I can explain: If the DIFFERENCE in the cutoff frequencies is much LESS than the mean frequency, the such a band PASS signal is known as narrow band signal.
