What does it mean for signals to have impedance? To me, impedance is kinda like an "extended resistance" that also includes phase shift $$Z = R + jX $$It makes sense to me that components like cap...
According to Signal processing and linear systems by Lathi, the transfer function $H(j\omega)$ does not exist for systems with poles in the RHP: - This makes sense to me, since $H(j\omega) = \fr...
The term "Discrete" uses to describe a signal with two modes, but is there a term to describe a signal with just one mode or with three or more modes? Question update: Also, isn't a wave with just...
I just want to know why the Linear time-invariant(LTI) systems are a rich class in Signal Processing. Ofcourse there are different systems but still LTI is stressed a lot in academia. Is there any ...
