is only true if time invariance does hold.
As usual, you nitpicked right; I stand corrected and rephrase.
"Every linar system can be seen as a combination of delays, adders and
amplifiers, and in case of time-variant systems, control signal sources
which can affect the parameters of the delays and amplifiers." (the
adders being seen as trivial).
(I once had this discussion with a teacher at university - Prof.
Terhard, some of you might be familiar with him, e.g. for the concept of
virtual pitch - where I claimed that every time-variant system can be
seen as a time-invariant system with additional input ports for the
control signals. However, this in generality turns a linear system into
a nonlinear one, and the whole discussion moot. Luckily, I discovered
that before him ;).
