Eye and Constellation Diagrams, Pt 2
Part 1 looked at the eye diagram, a simple yet powerful visual tool which reveals many specifics about the quality of a recovered bit stream. Part 2 looks at the constellation diagram, another powerful visual tool which is used to show the signal space of complex encoding schemes and relationship among the symbols. Q: Why […]
Learning SMPS the hard way
By Tahmid, EDAboard.com forum member SMPS is the toughest section in power electronics. For this subject, you require additional knowledge for choosing the active and passive parts used in SMPS circuits. The special type of parts often required in power electronics (i.e. for low-frequency applications) may not be suitable in the case of SMPS. When […]
