What is radio tuner?

A radio tuner is an electronic device that receives radio signals and allows the user to switch between different frequencies or stations. It is a critical component of any radio system and can be found in various forms such as standalone devices, car radios, and even on smartphones. Radio tuners work by using a radio frequency oscillator that generates a signal and an antenna that receives the transmitted radio signals. The tuner then selects a particular frequency and filters out noise and unwanted signals to provide a clear sound to the user. Depending on the type of tuner, it may have manual or automatic controls, and some models also have the ability to store preset stations.
