The circuit was designed to create ten different frequency bands to be handled by a single graphic equalizer to produce and maintain a predetermined area of frequencies. Graphic Equalizer – a common ...

We took a look at op amp integrators in the previous article, Op amps do integration, so it makes sense to round out the picture by covering differentiator circuits. Of course, differentiation is the ...

Using a single op amp and a properly selected resistor, this white-noise generator provides flat output versus frequency and speeds testing of circuit performance. The behavior of analog circuits can ...

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 ...

Electrical engineers will recognize the Bode plot as a plot of the frequency response of a system. It displays the frequency on the x-axis and the phase (in degrees) or magnitude (in dB) on the y-axis ...

Measuring tiny differences in high-voltage circuits usually requires specialized differential test probes, which are often expensive. Fortunately, it’s possible to build your own high-voltage probe ...

For an undamped LC circuit excited by an AC voltage source through simple phaser equations, we come to see that the circuit becomes short circuited at the resonant frequency. However if we analyze the ...

Google Quantum AI and Keysight joined forces to enhance Quantum circuit simulations with frequency-domain flux quantization Provides an extended library of quantum devices and a robust circuit design ...

Apple’s new device isn’t as unbiased as some high-end audiophile gear, but it’s pretty damn good for a sub-$500 smart speaker. The last of a three-part series of reviews of Apple’s new HomePod smart ...
