Bioinstrumentation design generally involves the planning and assembly of the various components shown schematically in Figure 1. The first step in bioinstrumentation design is to define a measurable physical or chemical parameter that will provide some useful information pertaining to a specific problem or area of interest. An appropriate sensor unit or input transducer is then selected to generate a signal when the desired parameter is detected. This signal is sent to a processing unit via a transmission link. Generally, output transducers or actuators receive the processed signal and generate a desired response.
