The first installment of this article series discussed the need to verify SPICE model accuracy and how to measure the open- and closed-loop small-signal AC output impedance of operational amplifier ...

Digital signals are fundamentally electromagnetic waves added together. The higher the data rate required, the higher the frequency of the waves required to generate the signals. Once the signal ...

Recent advancements in EMC-related products take many forms from DSP-based signal processing to higher frequency TEM cells to shielded video cameras. A major theme is ease of use, which may be ...

January 29, 2013. Anritsu announced today that it is conducting live demonstrations of its 32-Gb/s test solution featuring the Anritsu MP1800A BER Testers during DesignCon. Anritsu said it is also ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

Lock-in amplifiers were invented in the 1930s [1, 2, 3] and commercialized [4] in the mid 20 th century as electrical instruments that are capable of extracting signal amplitudes and phases in ...
