This circuit was found in Intersil's documentation from the 70's, being indicated for powering operational amplifiers. The circuit divides the voltage from a single source.
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...
