This article discusses how a real-world filter’s deviation from ideal behavior needs to be quantified and that shape factor and selectivity are tools to use in this process. It touches on how the impact of both resonator Q and the filter order (number of resonators in a design) can influence a filters behavior in the transition band. And we have seen how the topic of selectivity can expand out to influence the behavior and complexity of a receiver and how well it can perform relative to system level specifications such as ACR and ACS.
