This circuit provides reverse power polarity protection using a power MOSFET and a diode. The MOSFET must be current in accordance with the current of the protected circuit.
We found this oscillator in a documentation for radio amateurs from the 1970s. The circuit can use...
Many oscilloscopes have high impedance inputs that make it difficult to observe high frequency signals...
This is the receiver for the previous circuit we found in the December 1992 Radio Electronics...
