This signal injector and tracer (follower) was found in an old American documentation. The transistors can be general use and power is made with one or two common cells.
The basic purpose of this circuit is to apply an audio signal to a video carrier for sound and...
Audio frequencies in the 300 Hz to 30 kHz range can be measured with this circuit. Transistors allow...
This circuit was obtained in an English publication of 1975. It is a circuit that stabilizes an...
