For following guidelines, ∆F is Frequency Deviation in Hz, Φ is Phase
Deviation in Radians, Fm is the Tone Modulation Frequency in Hz and
IF is Minimum IF Filter Bandwidth. General Guidelines for IF Filter
Selection are as follows:
For FM Modulated Signals:
IF = 4(∆F + F
m
)
For PM Modulated Signals:
IF = 4F
m
(Φ + 1)
For AM Modulated Signals:
IF =15 kHz, for F
m
≤ 1 kHz
