Document Summary

Note if a function is odd we only need to use the sines and if it is even we only need to use the cosines. 2/3 - static and dynamic characteristics of signals. An input signal often comes into a measurement device as a step function. Due to the time required to read the input the output signal is often of a lagging form. This is an important factor to be aware of when selecting a measurement device/system. A static signal is something like a temperature or pressure of a tire. A dynamic signal is something like an ac current or pressure in an internal combustion engine. Can be a periodic, step, etc. function in time. There are numerous ways that we can analyze input and output signals to learn about the variable we are measuring. Techniques include: classifying the signal and frequency analysis (histograms with a distribution). Analog (describes a signal that is continuous in time)
