Question

Identify the mathematical expression for amplitude modulated wave.

• A. $A_{c}\sin\left\lbrack \{\omega_{c} + K_{1}v_{m}(t)\} t + \varphi \right\rbrack$
• B. $A_{c}\sin\{\omega_{c}t + \varphi + k_{1}v_{m}(t)\}$
• C. $\{ A_{c} + k_{2}v_{m}(t)\}\sin\left( \omega_{c}t + \varphi \right)$
• D. $A_{c}v_{m}(t)\sin\left( \omega_{c}t + \varphi \right)$

Answer 1

Answer: (C)

$\{ A_{c} + k_{2}v_{m}(t)\}\sin\left( \omega_{c}t + \varphi \right)$

Answer 2

: $\{ A_{c} + k_{2}v_{m}(t)\}\sin(\omega_{c}t\varphi)$
