A tuned circuit (also called resonant circuit or tank circuit) acts similar to a resonator, similarly into a tuning fork.[eighteen] It has a all-natural resonant frequency at which it oscillates. The resonant frequency in the receiver's tuned circuit is altered through the consumer on the frequency of the specified radio station; this is named "tuning". The oscillating radio signal from the specified station brings about the tuned circuit to resonate, oscillate in sympathy, and it passes the sign on to the remainder of the receiver. Radio alerts at other frequencies are blocked because of the tuned circuit rather than handed on.[23] Bandwidth[edit]
