I just need a simple example, preferably one to do with voltage.
thanks for any help :)

An example of oscillations with two or more frequencies combined is a musical chord played on a guitar or piano. The individual strings or keys each produce their own frequency, but when played together, they create a harmonious combination of frequencies.
The combination of different frequencies in the oscillations creates a unique sound because the frequencies interact with each other, causing constructive and destructive interference. This results in a complex waveform that our ears perceive as a distinct sound.
In the case of two oscillations with slightly different frequencies, we can hear a pulsating sound called a beat. This is because the two frequencies periodically interfere with each other, creating a variation in the amplitude of the combined waveform.
The amplitudes of the individual oscillations determine the overall amplitude of the combined waveform. If the amplitudes are similar, the resulting waveform will have a higher amplitude. If one oscillation has a significantly higher amplitude, it will dominate the resulting waveform.
The frequency of the combined oscillations is calculated by finding the average of the individual frequencies. For example, if two oscillations have frequencies of 100 Hz and 200 Hz, the resulting combined frequency would be (100 + 200)/2 = 150 Hz.
