In practical terms, low-frequency wiring is generally considered to be ‘safe’, while higher frequency circuits require special considerations, including impedance (Z) matching. Where the cut ...

We’ll write about it! What’s up with input impedance? You hear people talking about it, but why does it matter? And impedance matching? Let’s break it all down. First of all, impedance is ...

How difficult the driver/drivers are to move is the part of what makes up the speaker's impedance, which is rated in ohms.

Marelli is bringing one of the most powerful tools for lab-testing EV batteries—electrochemical impedance spectroscopy (EIS)—under the hood.

University College London revealed a 30MHz impedance spectroscopy IC for analysing biological samples at ISSCC in San Francisco this week. The chip exhibits a 92.7dB signal to noise ration and 99.6% ...
