Making a microcontroller perform as a frequency counter is a relatively straightforward task involving the measurement of the time period during which a number of pulses are counted. The maximum frequency is however limited to a fraction of the microcontroller’s clock speed and the accuracy of the resulting instrument depends on that of the clock

[JanHerman] knows that tuning musical instruments is all about precision and that precision is measured in a logarithmic unit called a cent. A cheap tuner unit might be accurate to 1.5 cents which sounds good until you look at one for ten times the price and find it is accurate to 0.1 cents. So you

A radio receiver is always a fun project. [Jayakody2000lk] decided that his new superheterodyne design would use an Arduino and it looks like it came out very nicely. The system has four boards. An off-the-shelf Arduino, a Si5351 clock generator board (also off-the-shelf), and two custom boards that contain the IF amplifier and mixer. The receiver started

A beach is always a relaxing summer vacation destination, a great place to hang out with a drink and a book or take a swim in the ocean. For those who need a more active beach-going activity with an electronics twist, though, metal detecting is always a popular choice too. And, of course, with an

What is the PCB? As far as Printed circuit board is concerned, it is a board which is used in electronics. It has many pathways or signal traces to support and electrically connect many electronic components with one another. Moreover, this board is designed with fiberglass or any other laminate material. What are the different

Infineon adds GaN (Gallium Nitride) to its power portfolio: CoolGaN™ and GaN EiceDRIVER™ ICs. The next essential step towards an energy-efficient world lies in the use of new materials and technologies. Wide bandgap semiconductors enable greater power efficiency, smaller size, lighter weight, lower cost, or all together. Infineon is uniquely positioned in the power semiconductor

We were struck by how attractive [mircemk’s] Arduino-based frequency counter looks. It also is a reasonably simple build. It can count up to 6.5 MHz which isn’t that much, but there’s a lot you can do even with that limitation. The LED display is decidedly retro. Inside a very modern Arduino Nano does most of the

This verified reference design provides an overview of how to implement a three-level three-phase SiC-based DC: AC grid-tie inverter stage. The higher switching frequency of 50KHz reduces the size of magnetics for the filter design and enables higher power density. This verified reference design provides an overview on how to implement a three-level three-phase SiC

Introduction Frequency domain analysis is very important to know more about any system/ circuit or transfer function that we deal with. And the first thought comes to our mind about frequency domain analysis is “Bode plot“. Bode plot is a combination plot of magnitude and phase difference of output vs. input of a cosine wave
