Am Radio Design
Objective: The objective of this lab is to design and AM Radio.
Introduction: Am radio uses Amplitude Modulation (AM), which works by varying the strength of the transmitted signal in relation to the information being sent. When you tune into an AM radio station, for example 1560 on the AM dial—the transmitter’s sine wave is transmitted the data at 1560,000 hertz. What this number essentially means is that the sine wave repeats every 1560,000 times per second. The data is modulated onto the carrier wave by changing the amplitude of this sine wave. The radio station uses and amplifier in order to amplify the signal. For large AM stations the signal is amplified to about 50,000 watts. After the signal has been amplified the radio station sends the radio waves out into space with the help of an antenna. This is essentially how data gets transmitted from an AM station onto a radio receiver. Now let’s take at the inner working of an AM receiver and required steps in......
