Figure 2 shows the electrical system (band-stop or notch filter). These circuits are used to "filter out" or attenuate input signals within a particular frequency band. For example, notch filters are used on aerospace vehicles to remove the mechanical vibrations that are transmitted to the onboard sensors such as gyroscopes and accelerometers. Derive the transfer function G(s) of the band-stop or notch filter where voltage eo is the desired output and source voltage ein() is the input. L Output voltage...
