Description: The project is conducted in the assembly of an RC low-pass filter on a board and breadboard implementation of a program in LabView it possible to obtain filter characteristics.
To this end, it is necessary GPIB control through the function generator in order to apply sinusoidal voltages to the filter. The frequencies used for the input signal, according to the statement, must obey the relation (fn +1) / fn = constant.
Acquiring the computer signal applied to the filter and the response signal using the acquisition card, determines the amplitude of the output signal of the filter and its phase relation to the input signal.
Once the acquisition of the above data, the program can outline the gain and phase characteristics of the actual filter, determine its cutoff frequency and sketch the curve of the ideal filter. Platform: |
