Detailed Solution
Download Solution PDF\(\rm SSB\) के लिए, सामान्य समीकरण निम्न है,
\(\rm {X_{SSB}}\left( t \right) = m\left( t \right)\cos {\omega _c}t \pm \hat m\left( t \right)\sin {\omega _c}t\)
\(\rm \;m\left( t \right) = \cos \left( {2\pi {f_m}t} \right)\), के लिए
हमें निम्न प्राप्त होता है,
\(\rm {X_{SSB}}\left( t \right) = \cos \left( {2\pi {f_m}t} \right)cos{\omega _c}t \pm \sin \left( {2\pi {f_m}t} \right)\sin {\omega _c}t \\ \ \ \ \ \ \ \ \ \ \ \ \ \ = {\rm{cos}}\left[ {2\pi \left( {{f_c} + {f_m}} \right)t} \right]\)
