This circuit generates output pulses with sequential delays. The delays can be programmed by the values of the resistors and the capacitor. The supply voltage can typically be between 5 and 12 V.
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...
