When two sinusoids of different frequencies are added together this results in?

Adding sinusoids with different frequencies results in a signal that is no longer sinusoidal. But is it periodic? If the frequencies of the added sinusoids are integer multiples of the fundamental, the resulting signal will be periodic. Figure 2: Adding sinusoids at 3, 6, 9 Hz produces a periodic signal at 3 Hz.

How do you add two sine waves with different frequencies?

You can't add two sines of different frequencies. This is a fundamental limit which much of math and physics takes advantage of. Its also the basis of the fourier transform. To put it simply, sines of different frequencies are orthogonal.

What happens when two waves of different frequencies are added together?

Answer and Explanation: If two waves of different frequencies are propagating in the same direction are added together, their amplitudes would alternately add up and cancel out. In words, alternating constructive and destructive interferences would occur. As a result, they would form wave packets known as beats.
