Audio Frequency Signal Generator Schematic
https://www.theprojectasylum.com/electronicsprojects/signalgenerator/signalgeneratorschematic.html
Audio Frequency Signal Generator Schematic. This is the schematic from the original article. In the upper left of the schematic is the frequency generator section. The bottom left is the power supply and the right half of the schematic is the counter / display section of the unit. The JU1 jumper in the schematic is the access point for external ...
Signal Generator - Audio Amplifier Design
https://renardson-audio.com/gen.html
A good place to start is by looking at how other designers have achieved better results with similar circuits. Going back to July 1981 a good example was published in Audio magazine, as part of a series of three articles by Bob Cordell: 'Build a High Performance THD Analyzer'.The generator circuit is shown as Fig.9 on page 39, and uses a very similar approach to my AFG/3.

This audio frequency generator is a triggered signal generator. When a positive pulse of about 6 volts (minimum) is fed to the circuits input , a modulated audio signal comes out of the output. The signal pattern is similar to a bird’s chirp. The pulse width of the trigger signal must be a minimum of 2.5 miliseconds.
Audio Tone generator circuit using 555, 741 IC
https://mechatrofice.com/circuits/audio-tone-generator
Op amp tone generator circuit. This circuit is a tone generator using an op amp. Here also the circuit is an astable multivibrator which generates a square wave signal around 3KHZ frequency. The 741 op amp can deliver only a small output current. So, if it has connected directly to a speaker, the generated sound will not have enough volume.
4QD-TEC: Audio signal (sinewave) generators

A low distortion Audio Signal Generator. The next circuit (above) is a better implementation of the Wien circuit: this uses the Wien in the normal fashion, in the positive feedback path and with negative feedback to maintain stability. The device marked Th1 is a glass bead type thermistor: some of these thermistors consist of a bead in an ...

This oscillator will easily work from 10Hz to 100kHz, making a very nice bench audio signal generator or a full-fledged function generator. Combining two of these function generators and modulating the one with the other, just about any alarm sound or police/ambulance siren can be synthesized.
