Calculating the main lobe width of Dirichlet kernel
There's no analytical solution for the general case. However, it's quite straightforward to compute that value using a few iterations of Newton's method. I've done that and the plot below shows the ...

Analysis of impulse response in downsampling problem
b 1): hint: $\sin(x) = \frac{1}{2j}(e^{jx} - e^{-jx})$
c 1): hint: do it in the $\mathcal{Z}$ domain: $U(z) = \frac{1}{2} (X(z) + X(z)z^{-1} \cdots)$

Practical Implications of DFT Eigenvector Formulations
The unitary scaling convention for the DFT is identical in scaling with its inverse and preserves energy across the transform or inverse transform:
$$ \begin{align}
\mathcal{DFT}\Big\{x[n]\Big\} & ...

Relationship between signal rate, data rate, minimum bandwidth
The value of the case factor (c) is not limited to specific numbers; it can take a wide range of values depending on the design and operational requirements of the communication system. The specific ...

jumps in spectrogram of frequency ramping
As you can (or should) clearly see, your signal is not correctly generated.
You want a linear sweep with duration $T = 1\,\texttt{ms}$ but you're defining the duration to be ...
