What is the difference between IIR and FIR filters in Hypex products?
All Hypex products use IIR filters by default, providing efficient, low-latency signal processing. FIR filtering is available as an optional feature for applications requiring extremely precise phase and time control. In short, IIR offers performance and efficiency, while FIR adds linear-phase accuracy and advanced tuning flexibility.
