👉 In digital electronics, a "unmodulated" signal is one where there are no changes in phase between adjacent samples of the signal. This means that all samples from the same sample rate have the same amplitude and frequency. For example, if you have a sine wave with a 44100 Hz sampling rate, it would be unmodulated because each sample has the same frequency and amplitude regardless of how many samples it is divided into. In contrast, if you had a signal that
