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
