LSIC Systems Linearity Satisfy Homogeneity and Additivity Can be summarized by Superposition If 𝑥 𝑛 → 𝑦 𝑛 and 𝑥 𝑛 → 𝑦 𝑛 , then 𝑎𝑥 𝑛 + 𝑏𝑥 𝑛 → 𝑎𝑦 𝑛 + 𝑏𝑦 [𝑛] Shift Invariance If then and Causality Output cannot depend on future input values
BIBO Stability Three ways to check for BIBO Stability: Pole-Zero Plot (more on this later) Absolute summability of the impulse response Given then the system is BIBO stable A bounded input yields a bounded output Ex: vs. Absolute Summability ௡ୀିஶ

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
