NettetThe instrumentation amplifier provides high input impedance to match the high output impedance of skin. The band pass filter removes frequency content out of the bandwidth of the EMG. Finally, the non-inverting amplifier provides enough gain to make the small EMG signal large enough to be usable. Nettet14. okt. 2016 · In Figure 1, a differential voltage is measured across R SHUNT, with R1, R2, C1, C2, and C3 providing input common-mode and differential-mode filtering. R3 and C4 provide output filtering for the INA, U1. U2 buffers the reference pin of the INA.
