The presence of the carrier wave is important because the frequency is determined by that signal. For instance, the audio on an FM station stops on the studio side, the silence is "broadcast" because the carrier wave is still transmitted and is picked up by the FM radio.The antenna in an FM radio system is important in the process of detecting and converting signal to something you can listen to. The antenna in many radios is a telescoping metal shaft that extends to an average of 2 to 3 feet long. The antenna isn't used in a directional pattern so much as it is used in a "taller is better" method where the strength of a given signal is increased by the height of the antenna. Many MP3 players that include FM radio, and most pocket FM radios, use the antenna cord as the antenna. Some pocket radios also include an external antenna jack to make reception easier. MP3 players often don't have AM radio included because the noise created by the processing of the MP3 side of the player would interfere with the AM signal, leaving the listener with only noise unless they lived within a mile of an AM transmitter.

载波的存在很重要,因为频率是由信号决定的.例如,FM调频台的演播室停止了音乐广播,这时的寂静无声也被“广播”出去了,因为电台仍然在发射载波,并被FM调频收音机接收.一台FM收音机的天线在检测广播信号并将其转换成人耳能听到的声音的过程中起到了重要的作用.许多种收音机的天线是一种可以伸缩的金属杆,伸展后的长度平均为2到3英尺.收音机的天线不采用方向定向模式,而可以说是采用了“越高越好”的模式,接收信号的强度随着天线高度的增加而增强.许多内置了FM调频收音机的MP3播放器,以及大部分便携式FM调频收音机,都使用天线绳作为天线.一些便携式收音机也包含了一个外部天线插口,以使信号接收更为方便.MP3播放器通常不内置AM收音功能,因为MP3信号处理时产生的噪音会干扰AM信号,除非收听者待在距离AM发射台1英里范围内,否则他们收听到的将只会是噪音.
