The simulation results in Simulink
5 Summary
We design a kind of simulation scheme of adaptive notch filter by introducing how to
use Matlab tool software to simulate adaptive algorithm. Simulation results show that
adaptive notch filter designed by Matlab language programming and Simulink mod-
eling has very good effect and performance. We can verify the correctness of Simulink
modeling by Matlab language programming. Because Simulink modeling is the more
intuitive and simple than Matlab programming, we don't have to remember usage of all
kinds of commands and parameters, can complete very complicated work with the
mouse, and modify parameters easily.
