Assumptions:\n - (Initial) DAQ is MCC USB-1208FS (available at BMI)\n 11-bit, max 6250 S/sec for each channel; sequential\n - Target Bandwidth: 195Hz\n - Sampling Rate 6240 S/s\n - Sensor resistance ~2MΩ\n - Respiration motion changes sensor resistance by < ±10%\n - Sensor resistance changes with handling; would require at\n least per-subject trimming if DC coupled.
Text Notes 750 7750 0 60 ~ 0
Open Questions:\n\n1. AC vs DC Coupling:\n - AC; no trimming, better UX, better tempco, cheaper\n - DC; captures all low-frequency signal that may be of interest\n\n2. Use chopper amps in signal path: Probably bad\n - Lower total noise for *extremely* small bandwidths (<5Hz?)\n - Lower offset (if DC coupled)\n

Problems:\n\n - USB-1208FS has fixed single-ended range of ±10V\n - Drop in upgrade to USB-1608FS (16bit and variable range)\n - Mitigated initially by running on 18V via two 9V batteries.\n\n - R202, R208, R212, R218; 39M only available in thick film. \n - More (slightly) 1/f noise and ±5% accuracy.\n\n - AC coupling isn't optional in this design. Rhodri keen\n to try AC route first; add cost / complexity later if needed.
