We explored using fast wavelet transforms to compress EKG samples for an ambulatory cardiac monitoring device, but the risks of regulators not understanding the math behind the compression meant we walked away from a ~3:1 compression of the sampled waveforms and attendant bandwidth savings.
- CamperBob2 7y agoI'm surprised bandwidth was a consideration at all given the slow signals involved. What's a typical Nyquist rate used when sampling an EKG?
- person_of_color 7y agoProbably 500 Hz. Haha
