Lead/Lag Compensators : Design + Demo

The bode plot indicates that the gain margin of the plant would be unaffected if a lead compensator is used but the phase margin would be improved. However, it is important to note that in a lead compensator as high frequency response has a high gain, noise at high frequency would also be amplified and this is an issue in a practical system and ...

Lead chamber process - Wikipedia

The lead chamber process was an industrial method used to produce sulfuric acid in large quantities. It has been largely supplanted by the contact process.. In 1746 in Birmingham, England, John Roebuck began producing sulfuric acid in lead-lined chambers, which were stronger and less expensive and could be made much larger than the glass containers that had been used previously.
