I am kind of confused. Does the radio transmitter modulate the waves or change it into alternating current. If it does both then which one is done first?
Thanks for your help.

A radio transmitter is a device that uses electromagnetic waves to send information through the air. It converts electrical signals into radio waves, which can then be received and decoded by a radio receiver.
A radio transmitter is used to broadcast radio signals, such as music, news, or emergency alerts, to a wide audience. It is also used in communication systems, such as radios, cell phones, and satellites.
A radio transmitter works by using an antenna to create an electromagnetic field. This field carries the radio waves, which are modulated with the desired information, such as audio or data. The transmitter then amplifies and broadcasts these waves into the air.
A radio transmitter typically consists of an oscillator, a modulator, an amplifier, and an antenna. The oscillator generates the radio frequency, the modulator adds the information to the signal, the amplifier boosts the signal strength, and the antenna broadcasts the waves into the air.
Radio transmitters are used in a variety of applications, including broadcasting, communication systems, radar systems, and wireless networks. They are also used in scientific research, such as in space exploration and radio astronomy.
