Electronics engineers {have to} {main} the 20 kind

engineers should master the 20 analog circuit
control of analog circuits is divided into 3 levels.
primary level is the proficient remember these 20 circuits, clearly the role of these 20 circuits. As long for the electronic enthusiasts, at the peak of studying automation, electronics and other electronic control level and vocational people should be able to memorize the 20 basic analog circuits.
intermediate class is apt diagnose the 20 circuits in the role of opener components, each component failure feature of the circuit be affected, the changes of dimension parameters, failure to master the components of the dispose ; qualitative analysis of the circuit signal stream, phase alteration; qualitative analysis of waveform changes in the process; qualitative knowing of the size of the circuit input and output impedance of the signal and impedance narrations. With wisdom of these circuits, you will maximum probable grow into electronics and industrial control equipment, great fix and livelihood mechanics.
perfected level is able to quantitatively calculate the 20 input and output impedance of the circuit, the output signal and the percentage of the input signal, the circuit signal current alternatively voltage and circuit parameters of the relationship among the circuit signal expanse versus frequency characteristics, phase vs. frequency characteristics of the circuit component parameters choices. Reached one advanced level, at a time you hope, a adored high-paying job - electronics and industrial control equipment evolution and chart engineers will be your premier choice vocation.
