First, the response of the odor sensors (e.g., a resistance change) needs to be measured and converted into an electrical signal (e.g., a voltage). This operation is performed by means of interface circuits. Second, the electrical signal undergoes analog conditioning (e.g., filtering) to enhance its informa- tion content. Third
process the output signal from sensors of a measurement system to be suitable for the next stage of operation. The function of the signal conditioning circuits include the following items: Signal amplification (opamp),. Filtering (opamp), Interfacing with µP (ADC), Protection. (Zener & photo isolation), Linearization, Current –
Measurement system comprises of sensors, transducers and signal processing devices. Sensor. It is defined as an element which produces signal relating to the quantity being measured [1]. According to the Instrument Society of America, sensor can be defined .. Hall effect sensors need necessary signal conditioning.
Many applications require environment or structural measurements, such as temperature and vibration, from sensors. These sensors, in turn, require signal conditioning before a data acquisition device can effectively and accurately measure the signal. Key signal conditioning technologies provide distinct enhancements to

I recommend it with no reservation, congratulating the authors for the job performed."" -IEEE Engineering in Medicine & Biology
We will begin this seminar with an introduction to the various aspects of the signal conditioning that is typically needed to bring the analog signals generated by a sensor into a form that can be processed by an embedded processor such as a DSC or microcontroller. Through most of the presentation, we will discuss some
