Relationship between fourier transform and fourier series

Transform looks right, but the logic afterwards needs some correction. $$ X(\omega) = -i \pi A \left(e^{i \alpha } \delta \left(\omega -2 \pi f_0\right)-e^{-i \alpha } \delta \left(2 \pi f_0+\...

Plot amplitude vs freqency in DB

You have two choices. You either maintain a linear grid and just replace the amplitude grid numbers with their respective dB values, or you can use a logarithmic grid with constant dB spacing. The ...
