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 response including the impulse response and step response, filter/amplifier with distributed gain, methods to estimating noise with given RTI and RTO noise specifications along with practical criterion for setting a filter to prevent aliasing.

 

In the first part of the two-part series exploring filter technologies and characteristics for dynamic measurements, PFI covers the filter amplitude, phase and transient response along with practical criterion for filter selections.
