Abstract: ABSTRACT A SIGNAL PRE-CONDITIONING SYSTEM The present disclosure relates to a signal pre-conditioning system. The system comprises a first circuit and a second circuit. The first circuit comprising a Programmable Gain Amplifier (PGA) that is configured to operate at a gain value selectable from a set of gain values, wherein the first circuit is configured to amplify transducer signal to generate amplified transducer signal. The second circuit electrically connected to the first circuit and comprising a plurality of Critically Damped Filters (CDFs). Further in the second circuit, the plurality of CDFs are connected in parallel and configured to filter the amplified transducer signal to generate a filtered amplified signal, at least one CDF from the plurality of CDFs is configured to operate at a frequency selectable from a frequency range based on operating gain value of the PGA, and the plurality of CDFs other than the at least one CDF is configured to operate at a fixed frequency.
