So, the statement "a tuner is a device for listening to radio broadcasts" is one of the definitions of this concept.
Today, such a receiver can be not only an independent device, but also one of the functions of modern mobile and other devices.
Many smartphones are equipped with a software radio tuner. Most often, using such a device, you can listen only to those channels that broadcast in the fm range.
In the age of the rapid development of technology, radio has not remained aloof from progress either. A new, digital way of signal transmission has appeared. If a person wants to listen to programs in this format, then he needs to purchase a special receiver. However, those who prefer to enjoy their favorite radio programs while at home may not need to purchase special equipment for this purpose.
The function of listening to digital radio is in almost all television receivers designed to watch satellite or dvb t2 broadcasts. If you do not yet have such a device, then most likely you will have to purchase it in the near future, since our entire country will completely switch to digital television in 2019. Federal channels will gradually turn off the broadcast of their programs in an analog way. It is planned that the complete abolition of traditional TV will take place in the summer of 2019.
