This transistor curve tracer was described in a December 1969 Radio Electronics article. It consists of a ladder-type signal generator that applies stepped voltages to the transistor under test.
Bipolar transistors are types of general use like BC548, while the power MOSFET can be of any type...
This circuit generates a signal rich in harmonics that extends up to close to 1 GHz, serving for...
This second-order low-pass Salen-Key filter was obtained from an American 1980s documentation. Formulas...
