radio unit


Kiss radio audience id say is young teenagers from ages 13 to 19.
Watching TV is different to listening to the radio because when you’re watching TV you’re actually watching an image with colour as well as sound whereas when you listen to the radio all you hear is sound. I've noticed that usually when you get a weather or news report on a radio they often have music playing very low in the background but there’s a lot less of that on TV.
AM and FM are forms of sound transmission in the form of radio waves. AM stands for Amplitude Modulation while FM stands for Frequency Modulation. Modulation is the manipulation of radio waves in order to transmit a meaningful (and translatable) signal. Morse code over electrical wires is modulation in that the series of dots and dashes are a standard code. AM and FM are different in how the radio wave is modulated. AM uses amplitude (or overall strength of signal) to transmit the message. FM uses frequency modulation (or manipulating the "spaces" between the radio waves) to transmit the message.
