Lecture 11: 16-12-2021¶

Bandwidth limitation with phantom zeros

Presentation

The presentation “Bandwidth limitation with phantom zeros” discusses a way of limiting the bandwidth of negative feedback amplifiers using phantom zeros. With this technique the bandwidth of the servo functions is increased at the cost of reducing the transfer. By doing so, the quality of processing out-of-band signals can be improved. This reduced the IMD resulting from out-of-band interference signals.
