We found this circuit in an old oscilloscope publication. With it, it is possible to observe the B / H curve (hysteresis) of an inductor in a common oscilloscope.
This circuit is from a 1969 Electronics World. It generates 100 kHz sinusoidal signals determined...
This continuity test is very simple to assemble and has great sensitivity detecting the presence of...
The operational amplifier used in this circuit is not common today, but it can be implemented with...
