Amplituudnihke

Amplituudnihke, also known as amplitude modulation (AM), is a technique used in telecommunications and signal processing to transmit information by varying the amplitude of a carrier wave in accordance with the information-bearing signal. This modulation process allows for the efficient transmission of audio, video, and other data signals over long distances.

In AM, the amplitude of the carrier wave is modulated by the amplitude of the information signal. The resulting modulated wave is then transmitted through a medium such as the air or a cable. At the receiving end, the modulated signal is demodulated to recover the original information signal.

AM is widely used in broadcasting, particularly for radio and television transmissions. It is relatively simple to implement and requires less complex equipment compared to other modulation techniques. However, AM is susceptible to interference and noise, which can degrade the quality of the received signal.

Despite its limitations, AM remains a fundamental technique in the field of communications. Its simplicity and robustness make it a valuable tool for various applications, from amateur radio to industrial communications. Understanding the principles of AM is essential for anyone working in the field of telecommunications and signal processing.
