India’s Airwaves Shift From Towers To Phones: DTT To D2M
– Advertisement – As analogue fades, India eyes a digital leap with DTT and D2M—reshaping how we watch TV, stream on mobiles, and access free public broadcasting without the internet. Bringing TV into the digital era The analogue TV is obsolete for now, and all the analogue transmitters of Doordarshan (DD) have been shut down…

Single sideband generation
The phasing method In radio communications, one way to generate single sideband (SSB) signals is to make a double sideband signal by feeding a carrier and a modulation signal into a balanced modulator to create a double sideband (DSB) signal and then filter out one of the two resulting sidebands. If you filter out the…

A high-performance current source
The ever innovative and prolific Mr. Woodward has offered “PWM-programmed LM317 constant current source,” an intriguing programmable constant current source which elicited a lively conversation in its comments section. A Zen paradox arose: if the addition of a capacitor between ground and the LM317 ADJ pin reduces the power supply-induced ripple current delivered to the…

The transformative force of ultra-wideband (UWB) radar
UWB radar is an augmentation of current ultra-wideband (UWB) ranging techniques. To understand the technical side and potential applications of UWB radar, let’s start at the beginning with the platform it builds on. UWB is a communication protocol that uses radio waves over a wide frequency bandwidth, using multiple channels anywhere within the 3.1 to…

Semiconductor industry strategy 2025: Semiconductors at the heart of software-defined products
Electronics are everywhere. As daily life becomes more digital and more devices become software defined and interconnected, the prevalence of electronics will inevitably rise. Semiconductors are what makes this all possible. So, it is no surprise that the entire semiconductor industry is on a path to being a $1 trillion market by 2030. While accelerating…

The (more) modern drone: Which one(s) do I now own?
Last September, I detailed why I’d decided to hold onto the first-gen DJI Mavic Air drone that I’d bought back in mid-2021 (and DJI had introduced in January 2018), a decision which then prompted me to both resurrect its long-drained batteries and acquire a Remote ID module to get it copacetic with current FAA usage…

Connecting The Smart City
– Advertisement – We live in an increasingly urban world. The United Nations (UN) estimates that more than 55 percent of us live in an urban environment and predicts that this will grow to nearly 70 percent by the middle of the century. This population growth comes at a time when we as individuals have…

Arduino Projects: Ideas for Engineering Students
Embarking on a journey in engineering can be as exciting as it is challenging. For many engineering students, hands-on projects are invaluable for learning and applying theoretical knowledge. One of the most versatile platforms for these projects is Arduino, an open-source electronics platform. Arduino’s user-friendly interface and extensive library make it an ideal starting point…

Building a low-cost, precision digital oscilloscope
Editor’s note: In this DI, high school student Tommy Liu modifies a popular low-cost DIY oscilloscope to enhance its input noise rejection and ADC noise with anti-aliasing filtering and IIR filtering. Part 1 introduces the oscilloscope design and simulation. Part 2 will show the experimental results of this oscilloscope. A digital oscilloscope is one of…
