Dual Frequency Generator (IMD Tests)



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

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. 440 Hz + 442 Hz at the same level will produce a 2 Hz beat).
