Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...

Some sensors output a processed analog signal that is linear with respect to the physical quantity being measured. Some perform quantization as well and provide a digital output. Though it is easy to ...
