Filtering for Dynamic Signals, Part 2
Part two of a two-part seminar series exploring filter technologies and characteristics for dynamic measurements
In part two, Doug Firth, President of PFI, discusses filter transient (impulse and step) response, filter/amplifier with distributed gain, methods for estimating noise with given RTI and RTO noise specifications, and practical criteria for setting a filter to prevent aliasing.
In the first part of the two-part series exploring filter technologies and characteristics for dynamic measurements, Doug covers the filter amplitude, phase and transient response along with practical criteria for filter selections.
