From the conception of the frequency response testing of the several type filter. For the example: low pass filter, high pass filter, band pass filter, band reject filter. The solution of the cutoff frequency is difficult and take a lot of time. Therefore, the idea of a tool that find frequency response quickly and easier than manual method. Maybe no only the filter, if the range of source sufficiently wide band frequency, the other electrical circuit maybe tested by this tool. In this project we will study in the frequency response.
If we interested in the frequency response. We must provide the automatic frequency changed sine wave source, then apply this signal to the tested network, and keep the output as data for plot graph in the monitor of computer by C language program.
