Simulated and experimental frequency response of filtering and amplifying system. In order to make efficient investigation on the total amplification and filtering chain, we provide simulated and measured results. These are frequency response results that help us to make useful output signal level and bandwidth considerations. Both simulated and measured results provide a flat frequency response at the frequency range of interest. Also, these results indicate that the 50-Hz power line signal component exhibits extra low level that eliminates any output signal degradation and distortion mainly due to induction coil saturation effects
