# Linear vs Non linear distortion

I'm learning about distortion and I got stuck at

"What is the difference between linear and non-linear distortion?" (Also in frequency spectrum i.e. Amplitude and phase spectrum)

• Also I would like to know if a LTI system can cause Nonlinear distortion? – Avinash Baldi Apr 15 '19 at 4:42
• An ideal LTI system is linear by definition, so I guess the answer is clear (?) – Matt L. Apr 15 '19 at 7:06
