Raman Pumping as an Energy Efficient Solution for NyWDM Flexible-grid Elastic ...IJECEIAES
This paper investigates transparent wavelength routed optical networks using three dif- ferent fiber types NZDSF, SMF and PSCF - and validates the effectiveness of Hybrid Raman/EDFA Fiber Amplification (HFA) with different pumping levels, up to the moderate 60% pumping regime. Nodes operate on the basis of flexible-grid elastic NyWDM transponders able to adapt the modulation format to the quality-of-transmission of the available lightpath, exploiting up to five 12.5 GHz spectral slots. Results consider a 37node Pan-European network for variable Raman pumping level, span length and average traffic per node. We show that HFA in moderate pumping regime reduces the power consumption and enhances spectral efficiency for all three fiber types with particular evidence in NZDSF. In essence to that, introduction of HFA is also beneficial to avoid blocking for higher traffic loads.

True or false: 30 dBm + 30 dBm = 60 dBm?
Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field strengths and more. What is a decibel and how should we use it in our calculations? This Application Note is intended as a refresher on the subject of decibels.

Overview:
Electromagnetic interference is increasingly becoming a problem in complex systems that must interoperate in both digital and RF domains. When failures due to EMI occur it is often difficult to track down the sources of such failures using standard test receivers and spectrum analyzers. The unique ability of real-time spectrum analysis and synchronous time domain signal acquisition to capture transient events can quickly reveals details about the sources of EMI.
What You Will Learn:
How to isolate and analyze sources of EMI using an oscilloscope
Measurement considerations for correlating time and frequency domains
Near field probing basics

Attendees Will Learn:
An overview of switched mode power supplies
Common measurements (ie, what to measure and why)
Circuit loading and probing considerations
How instrument specifications impact measurement accuracy
Switched mode power supplies have become ubiquitous in electronics as they provide precise voltages including high power with very high efficiency. The efficiency of these power supplies requires low loss power transistors and the design requires measurement of highly dynamic voltages. Voltage levels can vary from millivolts to hundreds of volts in some applications.
In this webinar, the proper use of a digital oscilloscope to accurately measure these voltages will be discussed along with key aspects of instrument performance such as noise and overdrive recovery that affect the accuracy of the measurement.

In this seminar, the proper use of a digital oscilloscope to accurately measure these voltages will be discussed along with key aspects of instrument performance such as noise and overdrive recovery that affect the accuracy of the measurement.
Embedded systems increasingly employ digital, analog and RF signals all of which are tightly synchronized in time. Debugging these systems is challenging in that one needs to measure a number of different signals in one or more domains (time, digital, frequency) and with tight time synchronization. This session will discuss how a digital oscilloscope can be used to effectively debug these systems, and some of the instrumentation considerations that go along with this.
Wireless communications is a hot topic in technology today, driven by technologies like Wireless Networking, Cellular Telephony, Wireless Connectivity and Satellite Communications among others. Traditionally, wireless and RF communications has been one of the last bastions of analog engineering. With the advent of low cost digital, high speed integrated circuits, this too has become part of the digital domain. Although information transmitted today is largely digital high frequency signals whether digital or analog always behave like analog signals so having fundamental knowledge of this high frequency behavior is key.
Jitter measurements are commonly done taking small snapshots in time, yet systems often experience jitter from sources that occur over relatively long time intervals, which may not be accounted for using short time interval measurements methods.
In this webinar we will present the application of a real time, digital clock recovery and trigger system to the measurement of jitter on clock and data signals. Details of the measurement methodology will be provided along with measurement examples on both clock and data signals.
You Will Learn:
- What is Jitter
- Different types of Jitter
- Jitter measurement techniques
- Benefits of Jitter analysis using real-time DDC techniques
Differential structures such as backplanes and cables are the primary means for transmitting high speed serial data signals. Signal integrity of these systems is determined by the characteristics of the media such as insertion loss, crosstalk, and differential to common mode conversion.
Complete measurement of the mixed mode s-parameters is often performed by transforming single-ended s-parameters and assuming that the system is linear. In some cases, linearity cannot be assumed such as where active components are used.
This presentation describes how to measure true differential s-parameters which can be measured even in the presence of non-linear elements.
The USB 2.0 standard is widely deployed in both computer and embedded systems. Compliance testing for this standard includes signal integrity as well as a number of low-level protocol tests.
This presentation provides an overview of the test requirements for USB 2.0 compliance and provide background on each test case. Details of fixtures and signal integrity requirements are highlighted in detail.

Originally presented at DesignCon 2013.
Jitter is a very important topic in signal integrity for high speed serial data links. The jitter performance of clock signals used in generating the serial data signal is critical to the overall performance of these signals.
Phase noise is the most sensitive and accurate measurement of the performance of precision clocks.
This presentation covers the theory and practice for making phase noise measurements on clock signals as well as the relationship between phase noise and total jitter, random jitter and deterministic jitter. Measurements on a typical clock signal is also included.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
