Below is video tutorial about fundamental of signal conditioning tutorial part II. On previous video has covered about amplification, instrumentation amplifiers and filtering. On this part II video tutorial will cover about attenuation, isolation, linearization, and circuit protection.
Most data aqcuitition system input can measure voltages only within range 5-10 volt. Any voltages higher than this must be attenuated. To attenuated the voltages, we can use a voltage dividers. We can overcome the effect of voltage divider using unity gain, buffered amplifier and voltage dividers. Watch the video for further information.
