Active filters are ubiquitous in electronic design today, performing signal-frequency manipulation and conditioning for audio, IF (intermediate frequency), and digital-signal processing. The success ...

Several manufacturers offer op amp-based filter design tools [1-3]. Some tools choose off-the-shelf capacitor values, but others select non-standard ones. The option to alter passive component ...

OBJECTIVE: You will wind (and test) your own inductor, which you will also use in the AM radio project in a subsequent lab. You will also investigate the properties of capacitors by making a simple ...

Although many High-Q capacitors are available on the market their performance can vary widely depending on design and the quality of manufacturing, as Scott Horton of Johanson Technology explains to ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...
