An oscilloscope’s FFT function can tell you the frequency content of an acquired signal. Most digital scopes–even those costing less than $400–have the ability to perform a Fast Fourier Transform (FFT ...

These days we are spoiled with a lot of cheap test equipment. However, you can do a lot of measurements with nothing more than an oscilloscope. Add something like a signal generator and you can do ...

Specifications for analog-to-digital converters (ADCs) often include a fast Fourier transform (FFT) plot, such as the one shown in the figure, for a 12-bit ADC with a single-frequency input signal. In ...

What causes the degradation of aluminum electrolytic capacitors in power-supply designs? What is ripple current and how can it influence capacitors in power-conversion circuits? Step-by-step ...
