In this video tutorial, we review different techniques to evaluate the frequency response (Bode diagrams of gain and phase) of a linear system. We use an Analog Arts (http://analogarts.com/) SF880 for the analysis. Frequency response of a band-pass filter is evaluated using:
1- A sine wave generator and a 2 channel oscilloscope
2- A sweep generator and an oscilloscope
3- A sweep generator and a spectrum analyzer
4- A white noise generator and a spectrum analyzer
5- A frequency response analyzer
