Understanding the Local Oscillator in FM Receivers Introduction to FM Receivers FM (Frequency Modulation) receivers are integral components in modern communication, playing a pivotal role in the reception and decoding of radio signals. At the heart of these receivers are several key components, each contributing to the accurate processing and delivery of audio signals to …
frequency modulation
Understanding the Local Oscillator in FM Receivers Introduction to FM Receivers Frequency Modulation (FM) broadcasting is a method of radio transmission that uses changes in the frequency of a carrier wave to encode audio signals. Unlike Amplitude Modulation (AM), where the amplitude of the carrier wave is varied, FM varies the frequency. This method is …
The Importance of a Local Oscillator in Amplitude Modulation (AM)
Introduction to Amplitude Modulation and Local Oscillators Amplitude Modulation (AM) represents one of the foundational techniques in the field of communication, whereby the amplitude of a carrier wave is modified in accordance with the information signal. This technique, established in the early 20th century, remains pivotal due to its simplicity and effectiveness in transmitting both …
