Figure 4. A snapshot, in time, of two complex numbers whose exponents, and thus their phase angles, change with time. The notion of negative frequency is often troubling to engineers who've spent so ...

For a typical 1,024-sample time record, the corresponding frequency-domain spectrum would comprise 513 lines starting at zero (DC), extending to 75 MHz, and spaced 146.5 kHz apart. In other words, the ...

Performing measurements in the frequency domain with an MDO (mixed- domain oscilloscope) is straightforward and easy to set up. As with any spectrum analyzer, however, there are a few things that ...

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...
