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 ...

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 ...

Digital EMI receivers and real-time spectrum analyzers have become possible because of advanced ADC technology as well as the availability of high-speed DSP devices. Both instrument types sample ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

Joseph Fourier, born just 250 years ago, introduced a wonderful idea that revolutionised science and mathematics: any function or signal can be broken down into simple periodic sine-waves. Radio waves ...
