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 ...

Consider an undamped single degree-of-freedom system experiencing harmonic excitation whose equation of motion (EOM) is given by: Here omega n is known as the natural frequency of response. The ...

Recall from lecture that the total response is combination of the complementary solution and the particular solution. For harmonic excitation on a single-DOF system, this total response will be ...

Frequency response may well be one of the most misunderstood and frequently abused speaker specifications that any consumer has to deal with. An Axiom customer emailed me with the following query: ...
