We found this circuit in an Electronic Design. The main integrated circuit is the 4017. The frequencies are determined by the RC circuits as well as the duration of the generated pulse train.
Obtaining a voltage that is proportional to a current drained by a load can be important in...
The filter shown in the figure, suggested by National Semiconductor, only allows frequencies above...
This circuit allows you to find two diodes with equal characteristics. The circuit was found in a...
