-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%
-Text Notes 7000 6400 0    60   ~ 0
-Analysis Notes:\n\n  1. Steep digital filter 0.4-175Hz\n    - Respiration typically 0.25-0.33Hz\n    - Narrower useful bandwidth likely, modeling needed.\n\n  2. Correct for temporal offset of sample due to sequential sampling.\n\n  3. 2x decimation for 13-bit (ENOB) and noise reduction
-Text Notes 750  7750 0    60   ~ 0
-Open Questions:\n\n1. Trimming the bridge.\n  - Only makes sense w/ DC coupling\n  - Bad tempco\n  - Bad UX\n  - Needed for significant gain\n\n2. AC vs DC Coupling; both have advantages: AC is easier\n\n3. Reducing R202,R203,R206,R207 to decrease Johnson noise: Probably useless.\n  - Changing R202,R206 may break INAMP CMRR\n\n4. Use chopper amps in signal path: Probably bad\n  - Lower total noise for *extremely* small bandwidths (<5Hz?)\n  - Lower offset (if DC coupled)\n\n5. Driven shields for output: Probably useless\n  - Reduce error due to leakage current\n  - No analysis done to determine if this is significant\n  - Current DAQ isn't likely to benefit

-Problems:\n\n  - USB-1208FS has fixed single-ended range of +- 10V\n    - Reduces ENOB to 11 if running on 5V supply\n    - Drop in upgrade to USB-1608FS (16bit and variable range)\n    - Can be substantially mitigated initially by running on 18V via two 9V batteries.

-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%
-Text Notes 7000 6400 0    60   ~ 0
-Analysis Notes:\n\n  1. Steep digital filter 0.4-175Hz\n    - Respiration typically 0.25-0.33Hz\n    - Narrower useful bandwidth likely, modeling needed.\n\n  2. Correct for temporal offset of sample due to sequential sampling.\n\n  3. 2x decimation for 13-bit (ENOB) and noise reduction
-Text Notes 750  7750 0    60   ~ 0
-Open Questions:\n\n1. Trimming the bridge.\n  - Only makes sense w/ DC coupling\n  - Bad tempco\n  - Bad UX\n  - Needed for significant gain\n\n2. AC vs DC Coupling; both have advantages: AC is easier\n\n3. Reducing R202,R203,R206,R207 to decrease Johnson noise: Probably useless.\n  - Changing R202,R206 may break INAMP CMRR\n\n4. Use chopper amps in signal path: Probably bad\n  - Lower total noise for *extremely* small bandwidths (<5Hz?)\n  - Lower offset (if DC coupled)\n\n5. Driven shields for output: Probably useless\n  - Reduce error due to leakage current\n  - No analysis done to determine if this is significant\n  - Current DAQ isn't likely to benefit

-Problems:\n\n  - USB-1208FS has fixed single-ended range of +- 10V\n    - Reduces ENOB to 11 if running on 5V supply\n    - Drop in upgrade to USB-1608FS (16bit and variable range)\n    - Can be substantially mitigated initially by running on 18V via two 9V batteries.

-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%
-Text Notes 7000 6400 0    60   ~ 0
-Analysis Notes:\n\n  1. Steep digital filter 0.4-175Hz\n    - Respiration typically 0.25-0.33Hz\n    - Narrower useful bandwidth likely, modeling needed.\n\n  2. Correct for temporal offset of sample due to sequential sampling.\n\n  3. 2x decimation for 13-bit (ENOB) and noise reduction
-Text Notes 750  7750 0    60   ~ 0
-Open Questions:\n\n1. Trimming the bridge.\n  - Only makes sense w/ DC coupling\n  - Bad tempco\n  - Bad UX\n  - Needed for significant gain\n\n2. AC vs DC Coupling; both have advantages: AC is easier\n\n3. Reducing R202,R203,R206,R207 to decrease Johnson noise: Probably useless.\n  - Changing R202,R206 may break INAMP CMRR\n\n4. Use chopper amps in signal path: Probably bad\n  - Lower total noise for *extremely* small bandwidths (<5Hz?)\n  - Lower offset (if DC coupled)\n\n5. Driven shields for output: Probably useless\n  - Reduce error due to leakage current\n  - No analysis done to determine if this is significant\n  - Current DAQ isn't likely to benefit

-Problems:\n\n  - USB-1208FS has fixed single-ended range of +- 10V\n    - Reduces ENOB to 11 if running on 5V supply\n    - Drop in upgrade to USB-1608FS (16bit and variable range)\n    - Can be substantially mitigated initially by running on 18V via two 9V batteries.
