When you combine signals of the same or different frequencies. The resulting energy will be each original frequency and the sum of the frequencies and a frequency that is the difference of the two signals. This is the basis of heterodyning. This allows us to take an information signal and "upconvert" it to the RF realm for transmission. But the same processes can be used to "downconvert" or to beat one signal against the other to get a lower frequency representation of the energy. After hererodyning came out, newer radios were sold as superheterodyning as a marketing ploy. Sorry, but it is not more complex than that. This was back in the early 20th century and the idea of fair marketing or truthful processes were not legal issues like today. Have a nice day. Bob

There is no thermodynamic difference between them .
The short answer is "by superheterodyning it". A more complete answer requires information not given in your question.
A local oscillator is an electronic device used to generate a signal normally for the purpose of converting a signal of interest to a different frequency using a mixer. This process of frequency conversion, also referred to as heterodyning, produces the sum and difference frequencies of the frequency of the local oscillator and frequency of the input signal of interest. These are the beat frequencies. Normally the beat frequency is associated with the lower sideband, the difference between the two.
