As the title promises, I have spent some time for recapitulating the amplitude modulation and several reconstruction techniques. Today amplitude modulation isn’t very common, but was used for varoius applications like audio or signal transmissions in general. Math The amplitude modulation uses a high frequency signal $U_{C}$ which carriers the low frequency signal $U_{NF}$ into a higher frequency band. $$ \begin{aligned} U_{NF} &= \hat{U}_{T} + \hat{U}_{NF} \cdot cos\left( \omega t \right)\\ U_{C} &= \hat{U}_{C} \cdot cos \left( \Omega t \right) \end{aligned}$$ ...
