Found on an 80's Elektor, this circuit uses common components, being the diode a general purpose germanium. The coils select the frequency range of the indicator that reaches 60 MHz.
The advantage of this circuit lies in the fact that it does not need a negative source to generate...
We found this circuit in the Linear Applications Handbook of the 1994 National Semiconductor. The...
This regulated power supply can provide currents up to 1 A to a load. The transformer may actually have...
