The circuit was designed to create a low cost frequency meter that will cover the range of 1 Hz to 1 MHz with a digital indication using three 7-segment displays. 7805 – a 3-terminal 1A positive ...

This frequency meter project squeezes a lot of performance out of the ATtiny2313 microcontroller. That chip does all of the work, measuring the frequency on the input pin as well as multiplexing the ...

Intel and BOE have teamed up to bring laptops with dynamic refresh rate displays that go as low as 1Hz, using smart energy-saving technology. Intel and BOE announced a new partnership to introduce ...

The 1/f (one-over-f) low frequency noise region of amplifiers seems just a bit mysterious. Reader “tweet” asked for a discussion of 1/f noise—a challenging topic for a short blog. It’s also called ...

Don't miss out on our latest stories. Add PCMag as a preferred source on Google. Intel and Chinese display-panel manufacturer BOE have announced a new 1Hz refresh rate technology that can help reduce ...

Check out this nice simple method of achieving a 1Hz timebase. This is basically a lesson in dividing crystal frequencies in circuits to get the desired result. In this case, they are starting with a ...
