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 ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

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: ...

In motor applications, it’s suitable to respond to a varying input command with a nonlinear output response to allow compensation for a machine limitation and to provide a better user experience. For ...

An acoustical analysis of Apple's HomePod published Wednesday found the speaker boasts a relatively flat frequency response, characteristics often associated with accurate sound reproduction, but ...

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