In various industries and applications, it’s crucial to monitor the current and frequency of devices in real-time. These ...

In this project, I present a simple and efficient circuit based on an ATtiny85, capable of converting an analog voltage into a digital frequency (V/F). This small module allows me to measure the ...

Audio frequency detection is the process of identifying the pitch or dominant frequency of a sound signal. Three common methods used are Fast Fourier Transform (FFT), AutoCorrelation, and ...

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 ...

Taking into account the relationship between retinal and post-retinal vision disorders and color vision impairment, the objective of this work is to present a new configuration of a portable and ...
