Intermediate level Intermediate level Intermediate level Intermediate level is to analyze the circuit in the twenty role of key components, each component fails, the function of the circuit be affected, changes of measurement parameters, master of the fault components approach qualitative analysis of the circuit signal flow, phase change qualitative analysis of the change process the signal waveform qualitative understanding of the size of the circuit input and output impedance signal and impedance relations. With knowledge of these circuits, you will most likely grow into electronic products and industrial control equipment repair and maintenance technicians for the excellent repair and maintenance technicians repair and maintenance technicians repair and maintenance technician.
