# sir tell me what is the amplitude and frequency of upper and lower side band??

Modulated Wave

$e= E_{e}\sin \omega _{c}t$

$+\frac{m_{0}E_{c}}{2}\cdot \cos \left ( \omega _{c}-\omega _{m} \right )t$

$-\frac{m_{0}E_{e}\cdot}{2} \cos \left ( \omega _{c}+\omega _{m} \right )t$

So for  lower side band frequency is $f_{c} -f_{m}$ and amplitude is  $+\frac{m_{0}E_{c}}{2}$

So for  upper side band frequency is $f_{c} +f_{m}$ and amplitude is  $+\frac{m_{0}E_{c}}{2}$
