chap3.pptx
chap3.pptxssuser478d0e This document discusses pulse modulation and sampling theory. Pulse modulation uses discrete-time carriers where some characteristic of each pulse, such as amplitude, is varied continuously or digitally according to the message signal. Sampling theory states that a band-limited signal can be reconstructed from its samples if sampled at the Nyquist rate of at least twice the maximum frequency. Interpolation is performed by convolving the samples with a sinc function. Pulse-amplitude modulation varies the amplitude of regularly spaced pulses proportionally to the sample values.

How to Un-Obsolete Your Legacy Keypad Design
How to Un-Obsolete Your Legacy Keypad DesignEpec Engineered Technologies For any number of circumstances, obsolescence risk is ever present in the electronics industry. This is especially true for human-to-machine interface hardware, such as keypads, touchscreens, front panels, bezels, etc. This industry is known for its high mix and low-volume builds, critical design requirements, and high costs to requalify hardware. Because of these reasons, many programs will face end-of-life challenges both at the component level as well as at the supplier level.
Redesigns and qualifications can take months or even years, so proactively managing this risk is the best way to deter this. If an LED is obsolete or a switch vendor has gone out of business, there are options to proceed.
In this webinar, we cover options to redesign and reverse engineer legacy keypad and touchscreen designs.

Modern multi-proposer consensus implementations
Modern multi-proposer consensus implementationsFrançois Garillot Multi-proposer consensus protocols let multiple validators propose blocks in parallel, breaking the single-leader throughput bottleneck of classic designs. Yet the modern multi-proposer consensus implementation has grown a lot since HotStuff. THisworkshop will explore the implementation details of recent advances – DAG-based approaches like Narwhal and Sui’s Mysticeti – and reveal how implementation details translate to real-world performance gains. We focus on the nitty-gritty: how network communication patterns and data handling affect throughput and latency. New techniques such as Turbine-like block propagation (inspired by Solana’s erasure-coded broadcast) and lazy push gossip broadcasting dramatically cut communication overhead. These optimizations aren’t just theoretical – they enable modern blockchains to process over 100,000 transactions per second with finality in mere milliseconds redefining what is possible in decentralized systems.

Pune Makers ( http://www.meetup.com/Pune-Makers/ ) 8 HOW TO CODE IN ARDUINO Once you have downloaded and installed/extracted the folder, you can directly run Arduino.exe, which will take you to its IDE. The IDE will look like the shown screenshot. error & status messages

Select "Arduino Uno from the Tools > Board menu (according to the microcontroller on your board). All the peripheral connected with Computers are using Serial Port. You can check port for Arduino Uno in Device Manger.

- 15. Pune Makers ( http://www.meetup.com/Pune-Makers/ ) 15 SERIAL COMMUNICATION “Serial” because data is broken into bits, each sent one after another in a single wire. Compiling turns your program into binary data (ones and zeros) Uploading sends the bits through USB cable to the Arduino The two LEDs near the USB connector blink when data is transmitted. RX blinks when the Arduino is receiving data. TX blinks when the Arduino is transmitting data
