Build a 3th order LP and HP filters that cover a signal range in between 0.2Hz and 150Hz an a gain of 10V/V each. Use C = 0.01µF with proper values of R's. Record your findings and include plots (magnitude and phase. Calculate the roll-off of the filter. Build an instrumentation amplifier having a differential gain of 80V/V. Choose the right differential input and common input signals to find the outputs and analyze the CMRR of the amplifier. What is the key component in the amplifier to increase or decrease the gain? Includes plots from the MultisimTM to all inputs and outputs.
