Typically, the signal coming from bio transducers are very complex and contain several frequencies and shapes. Many of these signals need to be pre conditioned, before an electronic or computer system analyzes these signals.Traditionally it is accomplished with the help of extended electronic filter circuits and wave shaping networks. However, if the signal extraction requirements, or the frequency values change, the entire pre conditioning elec-Q C a e (See Q4 ... Qo
