We found this circuit in a 1964 Electronic Design. Transistors can be modern general-purpose equivalents. The circuit converts a 1 MHz sinusoidal signal into a rectangular signal.
Found in the February 1990 Radio Electronics issue, this sophisticated 100 MHz probe uses a period...
This circuit uses only passive components and the instrument can be a microammeter or the lowest...
The circuit shown enables dynamic diode testing with an oscilloscope. We found this configuration in a...
