The development of a real-time optical waveform measurement technique with quantum-limited sensitivity, unlimited record lengths and an instantaneous bandwidth scalable to terahertz frequencies would ...

If you are making measurements on a one-time, intermittent, or “bursty,” signal, the usefulness of a conventional spectrum analyser is somewhat limited. It operates by scanning a narrowband receiver ...

This idea presents a C++ program that uses the complex class, which enables complex arithmetic. The Discrete Fourier Transform (DFT) is applied to the waveform stored ...

5G New Radio (5G NR) is the wireless standard defining the next generation of mobile networks. 5G will offer higher capacity than current 4G, enabling a higher density of mobile broadband users and ...

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 ...
