AMsignaalit

AMsignaalit refers to Amplitude Modulation signals. Amplitude modulation is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. In AM, the amplitude of the carrier wave is varied in proportion to the waveform of the message signal being transmitted. The carrier wave is a high-frequency electromagnetic wave that is used to carry the information signal. The information signal is typically a lower-frequency signal, such as audio.

The process of amplitude modulation involves combining the message signal with the carrier wave. This is typically done using a modulator circuit. The output of the modulator is an AM signal, which can then be amplified and transmitted. At the receiving end, a demodulator circuit is used to extract the original message signal from the AM signal. This process is known as demodulation or detection.

AM broadcasting is one of the oldest and simplest forms of radio transmission. It was widely used for voice and music broadcasting in the early days of radio. While FM (Frequency Modulation) has largely replaced AM for high-fidelity audio broadcasting due to its superior noise immunity, AM is still used for various applications, including long-range communication, amateur radio, and as a component in some digital communication systems. The simplicity of AM transmitters and receivers makes them cost-effective and easy to implement. However, AM signals are susceptible to noise and interference, which can degrade the quality of the received signal.
