| Since receiver developers when deciding about the intermediate frequency always have to find a compromise between the risk of mirror frequencies appearing (the appearance of a double of a strong signal as a "ghost station" in the wrong place on the dial should be prevented) and selectivity, the principle of the **double conversion superhet** or **double conversion** is used in high-quality receivers. | Since receiver developers when deciding about the intermediate frequency always have to find a compromise between the risk of mirror frequencies appearing (the appearance of a double of a strong signal as a "ghost station" in the wrong place on the dial should be prevented) and selectivity, the principle of the **double conversion superhet** or **double conversion** is used in high-quality receivers. | ||
