Do you still remember the days when you listen to the radio for news or for weather updates? It sounds so old school eh, but we enjoyed listening to it. Radio media has a big impact to each and everyone of us. It was a form of technology that would give us some sort of information.
But what is radio communication? In radio communication systems, information is carried across space using radio waves. The modulation signal is also associated degree audio signal representing sound from a electro-acoustic transducer, a video signal representing moving pictures from a video camera, or a digital signal consisting of a sequence of bits representing binary information from a pc. The modulation signal is applied to a sender.
Do you still remember the different radio modulation methods? Here are some few modulation methods:
- AM – Amplitude Modulation
- FM – Frequency Modulation
- FSK – Frequency Shift Keying
- OFDM – Orthogonal Frequency Division Multiplexing
Some of this modulation are so complex and we don’t think the new generation knew about it. So this still boils to my question is Radio Media still popular?
