LOTO lesson 3: frequency response curve of surveying and mapping - three groups of different paramet

Time:09-19

In work and project, often a function of signal conditioning circuit module, or filtering, or zoom in, or decay, or impedance transformation, these function circuit module can be passive resistance capacity, can also be active the op-amp circuit, also may be more complex systems, but they were the most important characteristics of signal conditioning is the frequency response curve, at this point, for us, they are the same a black box system,

Most of the time, we need to know its frequency response curve for system design and verification, this video is used in a simple RC filter to demonstrate we are faced with such a black box system, if use LOTO oscilloscope and signal generator module frequency curve drawing,




Oscilloscope PC software comes with frequency response curve drawing function, as long as good frequency sweep signal source module Settings step by step and frequency range, and can automatically draw the linear or index DB frequency response curve plotting,




Process video as follows:
