Two Tone Signal Generator

The tone generator can play four different waveforms.

Two tone signal generator.

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. This generator was conceived as a school project almost 20 years ago. 440 hz 442 hz at the same level will produce a 2 hz beat. When you find a frequency that seems to match your tinnitus make sure you check frequencies one octave higher frequency 2.

Simply enter your desired frequency and press play. Sine square sawtooth and triangle. A dual frequency tone generator will help you design your own imd tests or experience the beat of two oscillators. Knowing your tinnitus frequency can enable you to better target masking sounds and frequency discrimination training.

Circuit components such as amplifiers can be tested using the two tone method with a test setup like that shown in the figure. 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. 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. Free simple and easy to use.

The signal generator program turns the rfzero into a semi professional gpsdo controlled signal source from 2289 hz to 200 mhz and beyond. 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.
