Note: Most of these filters allow either double- or single-precision computation. Double-precision should be used unless the DSP is running out of resources. Single-precision should not be used for signal content below 1/10 the sampling frequency (5kHz for a typical 48kSPS system), or for high-Q filters.
The Filters library of the Toolbox lets you access numerous filter / EQ blocks for shaping the frequency content of your signal. The following blocks are available:
FIR Filters
Second Order Filters
- General (2nd Order); This page contains coefficient formulas for most second-order filters in SigmaStudio.
- General (2nd Order)/Slew Ext (Slew Rate Control from Pin)
- General (2nd Order)/Lookup (Pin selects from a table of similar second-order filters)
- General (2nd Order)/Index Selectable (Pin selects from a table of arbitrary second-order filters)
First Order Filters
Miscellaneous
The topic pages in this book contain specific information about the individual blocks. Be sure to take a look at the Filter Examples page to see sample schematics using some filter blocks.
To view the response of a filter's settings, drag a filter block into the workspace attach a Simulation Stimulus block to the input and a Simulation Probe to the filter's output. Now Click the Probe button Stimulus button. Take a look at the Filter Examples.
