Bias Tees are RF components that are used whenever you need to couple a DC, power or low-speed control signal onto an RF signal path. This video discusses the basics of Bias Tees, how they work, examples of practical...
In this video, the presenter will show you how he modified a common power bank in order to cut down its ridiculously long charging time. He will also explain the power bank circuit. Parts list: 1x Powerbank 1x 4PDT Switch 1x 2S Protection Circuit 1x...
Battery level indicator indicates the status of the battery just by glowing LEDs. For example six LED’s are glowing means battery capacity 60% remains. This article gives you an overview of how to design a battery level indicator. You...
This video discusses the basics of ferrite beads and their uses for basic filtering applications. It discusses and demonstrates how ferrites act as resistors at high frequencies, and how this is used for EMI/RFI Suppression, improved power supply filtering,...
In this video, the presenter will be explaining good, bad and ugly aspects of switching time measurements on bipolar transistors (BJTs). We find that the switching time measurements (rise time, fall time, delay time and storage time) are all highly...
This video will unveil the complexity and science behind flying a helicopter. The presenter will show you all of its operations in the form of an animation tutorial. After going through the physics behind the helicopter flying, you will...
Dolby Atmos and DTS:X are new surround sound technologies that are very much different from traditional speaker channels. How do they work, and what makes them special? In this video, the presenter is going to explain you the same. Courtesy: Techquickie
