Two Tone Signal Generator

A dual frequency tone generator will help you design your own imd tests or experience the beat of two oscillators.

Two tone signal generator.

440 hz 442 hz at the same level will produce a 2 hz beat. Free simple and easy to use. Knowing your tinnitus frequency can enable you to better target masking sounds and frequency discrimination training. The signal generator program turns the rfzero into a semi professional gpsdo controlled signal source from 2289 hz to 200 mhz and beyond.

In addition to a single frequency source the rfzero can also generate two tone i q h3a or spread spectrum signals or be used as a sweep generator. Circuit components such as amplifiers can be tested using the two tone method with a test setup like that shown in the figure. Sine square sawtooth and triangle. Assigned to build a circuit board we made a two tone generator that used two twin tee oscillators with the high oscillator locked to the third harmonic of the low oscillator with a small capacitor.

A beat is an interference between two sounds of slightly different frequencies perceived as periodic variations in volume whose rate is the difference between the two frequencies e g. Two signal generators set to two different frequencies f1 and f2 are fed into a power combiner through circulators the combiner needs to have good isolation to prevent the signal from one generator being sent to the output of the other. You will hear a pure tone sine wave sampled at a rate of 44 1khz. The tone generator can play four different waveforms.

When you find a frequency that seems to match your tinnitus make sure you check frequencies one octave higher frequency 2. This generator was conceived as a school project almost 20 years ago.
