This integrating circuit multiplies the time that can be obtained with a 555 timer. We find it in an Electronic Design from the 90s. The circuit uses components that are still common today.
This circuit assumes that a pulse produced by S1 has a constant duration determined by R1 and C1....
This circuit was obtained from an ancient American documentation. The coil consists of 80 to 100...
This circuit was found in Raytheon's 1967 documentation. The circuit uses an operating of the era,...
