Found in old documentation, this receiver for the mid-wave range uses transistors from the era. In fact, modern general-purpose equivalents can be used.
This signal injector circuit, an astable multivibrator, was found in a 1971 magazine. The circuit can...
When the base of the general purpose transistor is grounded the circuit produces a signal that is given...
This relaxation oscillator, simulated in the Multisim Blue, produces two different signals. The...
