In a Roman context, ‘son of god’ referred to the emperor of Rome. After Julius Caesar’s death he was deified by the Roman senate and was dubbed Divi Iulius or ‘the divine Julius.’ As such, his adopted successor, Octavian, upon his death and during his lifetime as emperor was called ‘Divi Filius’ or ‘son of god.’ Octavian’s adopted son Tiberius received the same honorary title. Under the Roman Empire, the emperor was literally worshiped as a god. In Jewish contexts, the ‘son of god’ refers to the king of Israel. In 2 Samuel 7:14 God relays that the new king of Israel will be his son and he will become his father.
Note on the left that when the carrier wave of FM radio is modulated with sound that the distance between the waves, or the frequency of the carrier wave, changes. Thus, AM radio works by changing the amplitude of the carrier wave and FM radio works by changing the frequency of the carrier wave. Frequency Response.
