Hi,
I need some information about Myoware (https://www.sparkfun.com/products/13723).
I’ll attach the picture which shows the biopotential chain due to raw and envelope signals are processed.
I need to understand something more about the technical features of this chain, then:
a) Instrumentation amplifier I think could be adjusted based on the potentiometer, right?
b) High-pass filter: which is the cutoff frequency?
c) Full-wave rectifier: this part just rectify the signal? Deleting the negative component, right?
d) Difference Amplifier: Here how much is it the gain?
e) Integration amplifier: And what does it do over the signal?
I didn’t find this info in any websites, and not even in his patent (https://patents.google.com/patent/US10010259B2/en).
Please, may someone has already faced up this problem and could help me? Your help would be really appreciated.
Thank you.
