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.

How to Build a Sine Wave Generator with a 555 Timer Chip
http://www.learningaboutelectronics.com/Articles/Sine-wave-generator-circuit-with-a-555-timer.php
The sine wave generator circuit that we will build is shown below. The breadboard schematic of the above circuit is shown below. So, first, for the power requirements of this circuit, we use 4.5V to the 555 timer chip. This 4.5V goes to pin 8 and pin 4. Pin 1 is grounded.

The output level of the sine wave signal is around 500mV RMS. 3) Using Audio Amplifier LM380 The circuit is built around an audio power amplifier device (IC1) utilized in a phase shift oscillator circuit. A three-section phase shift circuit is used to provide feedback between the output and the inverting (−) input of IC1.

Figure 1 shows the schematic for the quick sine wave generator: Figure 1 This circuit generates a sine wave by first generating a square wave, at the required frequency, with amplifier A1 that is configured as an astable oscillator with the frequency determined by R1 and C1. The two-pole low pass filter, using A2, filters the square wave output ...

Another dimension in sine wave oscillator design is stable control of amplitude. In this circuit, not only is the amplitude stabilized by servo control but voltage gain is included within the servo loop. A 100 Vrms output stabilized to 0.025% is achieved by the circuit of Figure 2. Although complex in appearance this circuit requires just 3 IC ...

The most critical component is the sine wave generator (single or multitone) and here a software-based direct digital synthesizer (DDS) can provide full flexibility with extremely fine frequency resolution and clock synchronization with the data acquisition system to perform coherent sampling to avoid leakage and FFT window filtering. Figure 1.

There used to be a couple of nice function generator ICs, the Exar XR2206 and Maxim MAX038. The XR2206 produced sine, square, triangle, ramp, and pulse waveforms from 0.01 Hz to 1 MHz; the Maxim the same from 0.1 Hz to 20 MHz. Both are now listed as obsolete on Digi-Key, but you can still find them around, e.g. here at Jameco.

Three ICs Produce Pure Sine Waves A TTL counter, an 8-channel analog multiplexer, and a 4th-order lowpass filter can generate 1kHz to 25kHz sine waves with a THD better than -80dB ( Figure 1 ). The circuit cascades the two 2nd-order, continuous-time Sallen-Key filters within IC 3 to implement the 4th-order lowpass filter.
