The integrated circuits used in this project are uncommon today. It is worth the idea for a microcontrolled project or with equivalents. We found this configuration in an old documentation.
This interesting circuit provides an output proportional to the input voltage, regardless of its...
The proposed circuit generates signals in the range between 9 kHz and more than 44 kHz, which, it is...
