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 ...
