Knock Measurement Resolution and Accuracy

I saw this presented in a Regional Group Meeting in Memphis in 2015.

This is an excellent example of why the new types of digital meters may provide much more stability and reliability in the measurement. By integrating the meter into a digital output, noise rejection is increased and errors in the measurement are greatly reduced. For low level signals noise is a huge factor in the overall system. This puts in into perspective for those of you still relying on the old analog display systems.
