A tuned circuit (also referred to as resonant circuit or tank circuit) functions just like a resonator, similar to a tuning fork.[30] It's a organic resonant frequency at which it oscillates. The resonant frequency with the receiver's tuned circuit is altered via the consumer for the frequency of the specified radio station; this is known as "tuning". The oscillating radio sign from the specified station will cause the tuned circuit to resonate, oscillate in sympathy, and it passes the sign on to the remainder of the receiver.
