10.3.7 Digital Filter Details
MSI 60 uses A/D converter oversampling and digital filtering to recording rate.
Digital filters eliminate ‘out-of-band’ noise
Cut-off frequency automatically adjusted to recording rate
Linear phase – no signal distortion
Example :
– 100 Hz recording rate (10 ms)
– < 40 Hz passband (> 99%)
– > 50 Hz stopband (< 1%)
Latency compensation – no filter delay in recorded data
– Filtering is (smart) averaging over several samples.
