BiQuad IIR Low Pass Filter for Arduino

BiQuadFilter

BiQuad IIR Low Pass Filter for Arduino

• Filters Arduino data type INT (int16_t)
• Highly optimized for 8 bit micros

Object creation:

BiQuadFilter filterObject(FreqCutoff, SampleRate);

The latest result is returned when adding data:

filteredData = filterObject.in(rawData);

The latest result can be accessed without adding data:

filteredData = filterObject.out();

Note: Currently Q is hard coded to 0.7071
