A high gain amplifier circuit that can be operated from a battery pack of 6 or 9 volt battery pack is shown here.The IC1 uA 741 is wired as a high gain non-inverting amplifier and its output is amplified by a pair of complementary transistors (Q1 & Q2) to drive the speaker.The negative feedback from the common emitter junction of the two transistor stabilizes the gain …
Audio Signal Tracer Schematic - Engineering Projects
https://bestengineeringprojects.com/audio-signal-tracer-schematic/
The complete circuit of the project; ’Audio Signal Tracer Schematic’ is given in fig. 1. The circuit uses two ICs; LM358 (IC1) and TDA2822M (IC2) as its chief component. IC1 consists of two operational amplifiers which get operated from a single power source with a wide voltage range from 3V to 32V.
Audio Signal Injector/Tracer – Electronic Circuit Diagram
https://freecircuitdiagram.com/898-audio-signal-injectortracer/
Here is the schematic diagram of the circuit: This signal tracer/injector uses 9 volts supply from battery. An alligator clip is recommneded for the ground probe, so you can works with one hand to hold the board, and the other hand to target the test probe.

Here is the schematic diagram of the signal injector/tracer circuit: Tracing an audio signal can be done using an audio amplifier, but using a handheld instrument would be more convenient, since you can make such instrument with special probes. As the opposite of tracing, injecting an audio signal is important too. Injecting an audio signal means connecting a certain point at your …

Dual audio signal tracer circuit Fig. 1: Circuit diagram of the dual audio signal tracer. Fig. 1 shows the circuit diagram of the dual audio signal tracer. It is built around LM358 (IC1) and TDA2822M (IC2). LM358 has two independent, high-gain, internal-frequency-compensated operational amplifiers, which are designed specifically to operate from a single …
Audio Signal Tracer Circuit - Radio Amateur 03-1967
https://www.radioexperimenter.us/rm-1967-03/info-rbi.html
The signal tracer shown in Fig. 57 uses a push pull output stage which produces more than adequate audio output to a miniature speaker with only ¡00 microvolts input. The output from the probe is applied directly to the 250 kilohm pot, which serves as a gain control and as a diode load when an rf probe is being used.
Pulse Generator And Signal Tracer Circuit Diagram
https://www.eeweb.com/pulse-generator-and-signal-tracer-circuit-diagram/
Pulse Generator And Signal Tracer Circuit Diagram. Posted Friday, April 26, 2013. This simple circuit generates narrow pulses at about 700-800Hz frequency. The pulses, containing harmonics up to the MHz region, can be injected into audio or radio-frequency stages of amplifiers, receivers and the like for testing purposes. A high-pitched tone can be heard from …

Figure 1 - Signal Tracer Schematic A suitable circuit is shown above. It's easy to build and inexpensive. The JFET input buffer provides high input impedance, and the LM386 amplifier IC can be used to drive a small speaker or headphones (the latter with caveats - see below).
Signal Injector and Tracer Circuit - EEWeb
https://www.eeweb.com/signal-injector-and-tracer-circuit/
In this circuit, the signal tracer is a low noise, high gain amplifier, with a small speaker for audible monitoring while the signal injector is an audio oscillator that acts as the signal source in the absence of an input signal being acquired. To switch between the trace and inject mode, a single pole double throw (SPDT) switch is used.
Signal Tracer Project - Rob's Radio-Active
https://www.robsradioactive.com/signal-tracer-project.html
The signal tracer works in much the same way with audio probe, except that an audio signal requires no detection, and usually does not require as much amplification, so it is fed to the volume potentiometer to the LM386. Double throw switches in both cases connect the signal where desired and disconnect from previous amplifier stages to avoid ...
