A radio receiver is an electronic devices that detects and demodulates and amplifies transmitted signals. Radio and television (TV) receivers are the most widely available entertainment devices in the world. AM radio uses amplitude modulation, the amplitude of the carrier wave is made to vary corresponding to the fluctuations of a sound wave, a television image, or other information which is to be conveyed. AM radio transmission is the oldest and simplest form of modulation and is used almost exclusively for aviation settings and is consistently used in directional assistance for marine applications. FM radio uses frequency modulation to provide high-fidelity sound over broadcast radio. Frequency modulation is a form of modulation which represents information as variations in the instantaneous frequency of a carrier wave. FM is transmitted in the very high frequency (VHF—30 MHz to 300 MHz) radio spectrum. Radio receivers having optional AM operation (amplitude modulation) and FM operation (frequency modulation) may have both AM and FM preselector stages downstream from a common preselection filter at the antenna input.
