dB and dBm
dB and dBmCeleste Yang dBm and dB are related but distinct units used to measure power in fiber optics. dBm refers to absolute power measured in milliwatts on a logarithmic scale, and is used to specify properties like laser output power and receiver sensitivity. dB refers to the ratio of input to output power and is used to measure losses in passive systems. To determine loss in dB, the input power in dBm is subtracted from the output power in dBm. While dBm is used for measurements, dB is used for loss calculations and specifying loss budgets. Technicians should use dBm for troubleshooting networks and dB for testing passive links.

DIGITAL COMMUNICATION: ENCODING AND DECODING OF CYCLIC CODE 
DIGITAL COMMUNICATION: ENCODING AND DECODING OF CYCLIC CODE ShivangiSingh241 Cyclic codes are a type of linear code where any cyclic shift of a codeword is also a codeword. This allows for efficient encoding and decoding using shift registers.
Encoding of cyclic codes can be done by dividing the message polynomial by the generator polynomial, with the remainder becoming the parity bits. Encoding circuits use shift registers with feedback to efficiently perform this division. Decoding uses the syndrome, which is computed by shifting the received word into a syndrome register. A decoder then attempts to match the syndrome to an error pattern, correcting errors one symbol at a time by shifting the syndrome and received word simultaneously.

Ec8491 Communication Theory-Unit 1 - Amplitude ModulationNimithaSoman Amplitude modulation (AM) varies the amplitude of a carrier wave based on the instantaneous amplitude of a message signal. In AM, the frequency and phase of the carrier wave remain constant while the amplitude is varied by the message signal. The modulation index, m, indicates the degree of modulation and is defined as the ratio of the amplitude of the message signal to the carrier amplitude. An AM signal produces a carrier wave along with upper and lower sideband frequencies that contain the message information.

Chapter 2c
Chapter 2cGabriel O'Brien Graded index (GRIN) optical fibers have a refractive index that decreases continuously from the core center to the cladding. This results in curved ray paths inside the core rather than straight lines, reducing intermodal dispersion. The optimal refractive index profile for minimizing dispersion is parabolic. Attenuation in optical fibers is due to various factors including material absorption, scattering, and bending losses. Rayleigh scattering increases at shorter wavelengths, while absorption peaks exist for hydroxyl and metal impurities.

“Why It’s Critical to Have an Integrated Development Methodology for Edge AI,...Edge AI and Vision Alliance For the full video of this presentation, please visit: https://www.edge-ai-vision.com/2025/06/why-its-critical-to-have-an-integrated-development-methodology-for-edge-ai-a-presentation-from-lattice-semiconductor/
Sreepada Hegade, Director of ML Systems and Software at Lattice Semiconductor, presents the “Why It’s Critical to Have an Integrated Development Methodology for Edge AI” tutorial at the May 2025 Embedded Vision Summit.
The deployment of neural networks near sensors brings well-known advantages such as lower latency, privacy and reduced overall system cost—but also brings significant challenges that complicate development. These challenges can be addressed effectively by choosing the right solution and design methodology. The low-power FPGAs from Lattice are well poised to enable efficient edge implementation of models, while Lattice’s proven development methodology helps to mitigate the challenges and risks associated with edge model deployment.
In this presentation, Hegade explains the importance of an integrated framework that tightly consolidates different aspects of edge AI development, including training, quantization of networks for edge deployment, integration with sensors and inferencing. He also illustrates how Lattice’s simplified tool flow helps to achieve the best trade-off between power, performance and efficiency using low-power FPGAs for edge deployment of various AI workloads.

War_And_Cyber_3_Years_Of_Struggle_And_Lessons_For_Global_Security.pdf
War_And_Cyber_3_Years_Of_Struggle_And_Lessons_For_Global_Security.pdfbiswajitbanerjee38 Russia is one of the most aggressive nations when it comes to state coordinated cyberattacks — and Ukraine has been at the center of their crosshairs for 3 years. This report, provided the State Service of Special Communications and Information Protection of Ukraine contains an incredible amount of cybersecurity insights, showcasing the coordinated aggressive cyberwarfare campaigns of Russia against Ukraine.
It brings to the forefront that understanding your adversary, especially an aggressive nation state, is important for cyber defense. Knowing their motivations, capabilities, and tactics becomes an advantage when allocating resources for maximum impact.
Intelligence shows Russia is on a cyber rampage, leveraging FSB, SVR, and GRU resources to professionally target Ukraine’s critical infrastructures, military, and international diplomacy support efforts.
The number of total incidents against Ukraine, originating from Russia, has steadily increased from 1350 in 2021 to 4315 in 2024, but the number of actual critical incidents has been managed down from a high of 1048 in 2022 to a mere 59 in 2024 — showcasing how the rapid detection and response to cyberattacks has been impacted by Ukraine’s improved cyber resilience.
Even against a much larger adversary, Ukraine is showcasing outstanding cybersecurity, enabled by strong strategies and sound tactics. There are lessons to learn for any enterprise that could potentially be targeted by aggressive nation states.
