We always enjoy [FesZ’s] videos, and his latest about FREQ function in LTSpice is no exception. In fact, LTSpice doesn’t document it, but it is part of the underlying Spice system. So, of course, you ...

Consider an undamped single degree-of-freedom system experiencing harmonic excitation whose equation of motion (EOM) is given by: Here omega n is known as the natural frequency of response. The ...

Recall from lecture that the total response is combination of the complementary solution and the particular solution. For harmonic excitation on a single-DOF system, this total response will be ...

Question: I have been reading about RF survey instruments and RF personal monitors and see the term “shaped-frequency response.” What does that mean? Answer: The shaped-frequency response technology ...

Graphene sounds: Schematic showing a graphene diaphragm, biased by a DC source, suspended between two perforated electrodes driven at opposite polarity. (Courtesy: A Zettl) Researchers in the US have ...

The last of a three-part series of reviews of Apple’s new HomePod smart speaker, including a subjective analysis of the device and an analysis of its spacial analysis technology. Apple’s claim that ...

a measure of the range (spectrum) of frequencies which a given system will be able to process. in humans our frequency response is normally 20 - 20,000 Hz with differing sensitivity depending on where ...
