Defining laser-beam power density. Power spectral density (PSD) is the measure of a signal's power content versus frequency. PSD gives designers an idea of how the power of a signal is distributed ...
Differentiation between power and energy density. The key role of GaN-on-SiC in achieving power-density goals. Applications seeking greater power density in their designs. To design robust power ...
The fast Fourier Transform (FFT), added to an oscilloscope or digitizer, permits measuring the frequency domain spectrum of the acquired signals. This provides a different and usually helpful ...
