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 ...

Let’s start our expla nations of loudspeaker measurement graphs with the most basic graph of a speaker’s behavior: the frequency response. Sometimes this is referred to as the amplitude response as ...

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 ...
