This circuit was found in a Signetics documentation from the 1980s. Next to the figure are the waveforms of the generated signals. The transistor admits equivalent.
In the figure we have an interface using an optical coupler and the comparator LM339 or any...
Figure bellow shows how n 4027 can be cascaded to form a divide-by-2. The maximum input frequency...
This relaxation oscillator, simulated in the Multisim Blue, produces two different signals. The...
