Tsunami is a signal generator built on the Arduino platform. It is the brainchild of London-based developer Nick Johnson at Arachnid Labs and has secured funding on Kickstarter for its commercial ...

[Todd Harrison] really has our number. Like him, we don’t want to spend money when we don’t have to, and hacking our own solutions is a lot more fun anyway. This time around he’s helping out a friend ...

Abstract: Frequency response method is an important approach in the design and analysis of plants and controllers. Bode plot is a simple technique to graphically represent a system frequency response.

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...

Real-time data acquisition from Arduino over serial and frequency analysis using the Fast Fourier Transform (FFT). Built as a practical signal processing toolkit for embedded sensor systems. Captures ...

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 ...

Abstract: The range of the frequency to be measured by a measurement device depends on the purpose of performing the measurement. The frequency measurement device is built specifically according to ...

2 Arduino Uno shields provide an oscillator, an attenuator and a detector, all under Arduino Serial or CLI control. Control and readout can be automated using e.g. a shell script. This circuit is ...
