How to use transfer function, impulse response, Fourier transform & convolution for system analysis?

In this video, I try to explain the relationship between the transfer function and the impulse response of a linear passive system like an RLC series resonant circuit as well as the Fourier transform and convolution for the analysis of such systems in frequency domain and time domain. For validation, I also do a pure numerical time domain analysis of the circuit and compare this with different simulations in LTspice.
