Can Linear Systems Effectively Store Information?

Click For Summary
SUMMARY

Linear systems can store information by utilizing memory to combine present and past input samples. These systems adhere to the superposition principle, meaning that the output from summed inputs equals the sum of the outputs from individual inputs. However, continuous input application can lead to data loss over time. This discussion clarifies the operational mechanics of linear systems in information storage, emphasizing their limitations in retaining data.

Hi all

Would it be possible to store information in a linear system?
 
Engineering news on Phys.org
The term "linear system" usually means some kind of filter which takes an input signal and produces an output signal. Such a filter is linear if it obeys the superposition principle: two summed inputs produces an output that's equal to the two inputs passed independently through the filter, and then summed afterwards.

In any event, a "linear system" may have some memory, usually used to add present samples of the input to past samples of the input. In this sense, you may store information in such a system, though, if you keep applying inputs, your data will eventually be lost.

Note: since this has nothing to do with astronomy, I'm moving it to general engineering.
