Signal Conditioning ( sig·n ə l k ə n dish· ə n·i ŋ ) ( communications ) Processing the form or mode of a signal so as to make it intelligible to or compatible with a given of a signal so as to make it intelligible to or compatible with a given device, such as a data transmission line, including such manipulation as pulse shaping, pulse clipping, digitizing, and linearizing. [www answers com] [www.answers.com] In electronics, signal conditioning means manipulating an analogue signal in such a way that it meets the requirements of the next stage signal in such a way that it meets the requirements of the next stage for further processing. Signal conditioning can include amplification, filtering, converting, range matching isolation and any other processes required to make range matching, isolation and any other processes required to make sensor output suitable for processing after conditioning.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
