Question

Write the formula for the band-width in amplitude modulation.

Open in App

Solution

If we have $f_{1}$ , $f_{2}$ and $f_{3}$ base band frequency signals in amplitude modulation and $f_{1} < f_{3} < f_{2}$ then,
Band width of amplitude modulated signal is given by,
Band width of AM signal $= 2 \times$ highest of baseband frequencies
$B W = 2 \times f_{2}$ ....... (here $f_{2}$ is the highest baseband frequency)
