Showing analytically that sampling exactly 1 period of a sinusoid yields a spectrum with no lobes in the DFT
To solve the roots, set:
$$e^{-j(\Omega-\omega_o)M/2}\frac{\sin \bigg(\frac{M+1}{2} (\Omega - \omega_o))\bigg)}{\sin((\Omega-\omega_0)/2)} = -e^{-j(\Omega+\omega_o)M/2}\frac{\sin \bigg(\frac{M+1}{2} (\...

Wavelets vs Windowed Fourier
Both transformations contain the same amount of information from the signal. But the choice of the representation makes some type of information more easily available (and other less).
What are these ...

Complex cross-correlation: conjugate first or second argument?
Since there seems to be quite a bit of discussion and previous answers, I'll add a different perspective of that from the PSD.
The PSD has two definitions:
\begin{align}
\phi(\omega) &= \sum_{n=-\...
