Filtering for Dynamic Signals, Part 1

Part one of a two-part seminar series exploring filter technologies and characteristics for dynamic measurements.

Doug Firth, President of PFI, discusses the signal-processing filter’s amplitude, phase and transient response along with practical criterion for filter selections.

 

In part 2 of the Filtering for Dynamic Signals series, Doug continues the series by exploring filter transient response including the impulse response, 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.
