Neural Impulse control Da’Janel Roberts Matthew Morgan Jonathan James

What?  An amplifying device to measure neural impulses  Buy or make?  Previous groups designs or new?

Requirements  High Gain (80dB and up)  Low Noise  Bandwidth (.5Hz to 50Hz)  As low a cost as possible

Previous groups  Brainmaster design  Instrumentation amp and LPF  Option 3 A new design?????

Brainmaster specs  Gain : 20,000 (86dB)  Bandwidth : 1.7Hz – 34Hz  CMRR : 100dB

Brainmaster schematic

Instrumentation Amp Specs  Gain : 20,000 (86dB)  CMRR : 116dB  Bandwidth :.2Hz - >50Hz

Instrumentation schematic

Flow Electrodes Amplifier Filters and A/D The Digital Converter Group

Plan  Build a Brainmaster board and test it. If it works, try and digitize the output.  If it doesn’t work then move to Instrumentation design and if that does not work….design a new one.  Send it along to the digital group.
