Frequency Modulation

Narrow-band FM versus Wide-band FM. What is the relation between modulation index and frequency deviation? What does transmission bandwidth of FM waves mean?

Solution

(C)Narrow-Band FM Versus Wide-Band FM

Relation between modulation index and frequency deviation

D=maximum frequency deviation/maximum modulation frequency

(d)transmission bandwidth of FM waves

The FM-channels assigns some channels up to 200KHz for 100 channels maximum
