Abstract: Chirp spread spectrum (CSS) signal is the heart of long-range (LoRa) modulation, also known as CSS modulation, and is used in long-range wide area network (LoRaWAN) in Internet of things ...

I was recently mulling on FPGA implementations of short length Fast Fourier Transforms (roughly N=30 to 100) at work. My dilemma was I needed a potentially arbitrary number of these in a scalable ...

Fundamental continuous and discrete-time signals and their implementations using Matrix laboratory. Concepts include CTS, DTS, Amplitude modulation, Amplitude demodulation, Double sideband suppressed ...

Multimode fibers (MMFs) are gaining renewed interest for nonlinear effects due to their high-dimensional spatiotemporal nonlinear dynamics and scalability for high power. High-brightness MMF sources ...

From experience, it seems no one actively tries to make their content inaccessible to their audience. Most people want to do the right thing, but they just don’t know how. After all, if the whole ...

Pulse-width modulation (PWM) is a technique for changing the amplitude of digital signals to control devices and applications that require power or electricity. It effectively regulates the amount of ...

Recent advances in deep learning have been providing non-intuitive solutions to various inverse problems in optics. At the intersection of machine learning and optics, diffractive networks merge ...

This tutorial is a part of series of MSP430G2 LaunchPad tutorials in which we are learning to use the MSP430G2 LaunchPad from Texas Instruments. So far we have learnt the basics of the board and have ...

There has been poor documentation online about using i2s on a RaspberryPi and in particular connecting a MEMs microphone. There is plenty of discussion but no clear tutorial and/or explaination. These ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...
