An unexpected revisit to my earlier post on mouse encoder hacking sparked a timely opportunity to reexamine quadrature encoders, this time with a clearer lens and a more targeted focus on their signal ...

The rapid development of the Fifth Generation (5G) networks encourages researchers to improve the Radio over Fiber (RoF) technique to achieve data rates of 10 Gbps and beyond. That led to a ...

Abstract: This paper investigates the effects of dispersion and phase noise on quadrature phase shift keying (QPSK) and quadrature amplitude modulation (QAM) systems, as well as their compensation ...

Error vector magnitude characterizes actual QAM signals’ deviations from their ideal locations due to nonlinearity and phase noise. Figure 1. Factors such as ...

If you’re completely new to Microsoft Word, you’re probably wondering where to begin. You’ve come to the right place because we’ll get you started. From what you see in the Word window to how to save ...

The combination of high-order modulation formats and linewidth-tolerant carrier phase estimation (CPE) can effectively improve spectrum efficiency and relax the limitation of laser linewidth. This ...

I am using an NI cDAQ-9184 with the NI 9411 module to read a quadrature encoder, but I can't seem to figure out how to get position readings from it. I have a voltage pulse signal wired into the 9411 ...
