WEEK 10 Activity Confirmation and doing simulation to get see the output Objective To get a smoother output waveform. Methods The instrumentation amplifier amplified the two input differential voltage between the two electrodes. Therefore the range gain of this instrumentation amplifier is amplifier is from 16.7 to 1125.6. Band pass filters consist of Low Pass … Continue reading 28 OCTOBER 2017
