एक आयाम माडुलित तरंग के लिए, जिसकी वाहक तरंग `( omega_c)` में, दो माडुलक संकेत (सिग्नल) `omega_1 ` तथा `omega_2 (omega_2 gt omega_1 )` हैं, के लिए आयाम और `omega` के बीच ग्राफ खींचिए।

Explanation

`upsilon (t )A (A_(m_1) sin omega_(m_1) t +A_(m_2) t + A_(m_2) t+ A _C sin omega_c t) + B(A_(m_1) sin omega_(m_1) t+ A_(m_2) sin omega_(m_2) t + A_c sin omega _(C ) t)^2`
` =A (A_(m_1) sin omega_(m_1) t + A_(m_2) sin omega_(m_2) t+A_C sin omega_(c) t) + B ((A_(m_1) sin omega_(m_1) t+_ A_(m_2) t)^2 +A_(c) ^(2) sin ^2 omega _c t + 2 A_C (A_(m_1) sin omega_(m_1) t + A_(m_2) sin omega_c t)`
`=A (A_1 sin omega _(m_1) t + A_(m_2) sin omega_(m_2) t+A _c omega_c t) + B[A_(m_1)^(2) sin^2 omega_(m_1) t+A_(m_2)+ 2 A_(m_1) A_(m_2) sin omega_(m_1) t sin omega_(m_2) t + A_(c)^(2) sin^2 omega_c t +2 A_C (A_(m_1) sin omega_(m_1) t sin omega_c t +A_c t +A_(m_2) sin omega_(m_2) + sin omega_c t ]`
`=A (A_(m_1) sin omega_(m_1) t +A_(m_2) sin omega_(m_2) t + A_c sin omega_c t ) + B [A_(m_1)^(2) sin^2 m_1 t +A_(m_2)^(2) sin omega_(m_2)^(2) t + A_(c)^(2) sin^2 omega _c t `
`+ ( cancel(2) A_(m_1) A_(m_2)) /( cancel(2)) [ cos ( omega_(c ) - omega_(m_1)) t- cos ( omega_(m_1) + omega_(m_2))t]`
`+( cancel(2) A_c A_(m_2))/( cancel(2) ) [ cos ( omega_C - omega_(m_2) t) - cos (omega_c + omega_m_2)t]`
` therefore ` विद्यमान आवृत्तियाँ
` omega_(m_1) , omega_(m_2) , omega_c`
` ( omega_(m_2) - omega_(m_1) ) , ( omega_(m_1) + omega_(m_2))`
` ( omega_c - omega_(m_1)) , ( omega_c + omega_(m_1) )`
` ( omega_c - omega_(m_2)) , ( omega_c - omega_(m_2))`
आयाम का `oemga` के साथ वक्र चित्र में दर्शाया गया है।
