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.
The time constant of this circuit is 100 x R1 x C1, which leads to the possibility of obtaining times...
This 3-transistor timer was found in the January 1994 issue of Electronics Now magazine. The...
An way to change the frequency of the previous oscillator (CIR112E) is to add a variable capacitor in the...
