When you measure RF emissions with a spectrum analyzer, you may need to measure the total power contained in a spread-spectrum signal. FCC part 15, subpart E (Ref. 1) requires these power measurements ...

Defining laser-beam power density. 2. Power spectral density is simply the Fourier transform of the signal. When we have a discrete case, as in Figure 2, the PSD can be calculated by using the fast ...

Silicon Laboratories Inc., a leader in high-performance, analog-intensive, mixed-signal ICs, introduced a web-based Isolator Power Consumption Calculator that streamlines the process of assessing ...

Because DACs don't usually appear alone in the signal chain, but instead are connected to voltage references and operational amplifiers (as reference buffers, for example), these additional components ...
