IIR Filter Second-Order-Section
2nd order IIR filter sometimes referred to as a 'bi-quad'.
Overview
2nd order IIR filter sometimes referred to as a 'bi-quad'. Internally, it has a fully pipelined architecture permitting the highest possible sample rates for IIR filtering. The SOS block is modular allowing any number of SOS blocks to be joined in series to implement higher order IIR filters.
Key features
- Key Design Features
- Synthesizable, technology independent VHDL Core
- Fully pipelined architecture for highest possible sample rates
- 16-bit signed input and output samples
- 16-bit fixed-point coefficients and scaling factor
- Internal overflow detection
- SOS coefficient matrix maps directly to filter coefficients
- Cascade SOS blocks in series for higher-order filters
- Small implementation size - requiring only 6 H/W multipliers
