5.2.3 Ringing
When you are tuning the S/O you may tune it so that the response rings. Ringing is caused when you attempt to tune
the S/O for too rapid response. Normally, the best solution is to reduce the bandwidth. The graph in Figure 5-5
shows a system that rings.

5.3 CURRENT LOOP TUNING
5.3.1 Theory of Operation
Tuning is the process of optimizing several parameters of operation, including response, bandwidth, and noise.
Tuning is based on control theory; the goal is to set loop gains with sufficient gain/phase margin while attaining the
required response.
