The Low – Cost Frequency Response Analyzer Project was introduced with an idea to analyze the frequency domain characteristics of physical objects. The basic idea was that as we analyze the properties and characteristics of a physical object from it’s time domain characteristics, we can apply a similar approach to it’s frequency response. We can use the specific frequency domain characteristics of an object to identify any problems associated with it , determine it’s shelf life and much more. T
