Closed-loop control systems are sometimes shipped from the factory with resonances and other operational difficulties that aren't supposed to be part of the package and are not well understood.

In a new episode of Elektor Engineering Insights, Elektor contributor Roberto Armani demonstrates practical methods for audio ...

Since the inception of electronic communications, frequency response has been the common measurement unit for most instruments. Even after the introduction of the feedback amplifier, frequency ...

Oscilloscopes are time-domain instruments, but because they digitize waveforms, oscilloscopes can process time-domain signals into the frequency domain. The FFT (Fast Fourier Transform), spectrum ...

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 ...

[Rolinychupetin] insists that his recent video is not a lecture but actually a “recitation” about Bode plots. That may be, but it is still worth a watch if you want to learn more about the topic. You ...

Christophe Basso is an Application Engineering Director at ON Semiconductor in Toulouse, France, where he leads an application team dedicated to developing new offline controllers specifications. He ...

Frequency response may well be one of the most misunderstood and frequently abused speaker specifications that any consumer has to deal with. An Axiom customer emailed me with the following query: ...

The presentation of loudspeaker measurements varies wildly from manufacturer to manufacturer. This means that, without independent analysis, consumers are left comparing specifications that were ...
