FosterSeeleyDetektor
The Foster-Seeley detector is an electronic circuit used primarily in radio receivers for demodulating amplitude modulated (AM) signals. Developed by Harry Foster and David Seeley in the early 20th century, this circuit is designed to extract audio or baseband information from a carrier wave with high linearity and stability.
The core principle of the Foster-Seeley detector involves comparing the phase and amplitude of the incoming
Its operation hinges on phase discrimination: when the input signal is in phase with the local oscillator,
However, the Foster-Seeley detector has limitations, such as sensitivity to frequency offsets and difficulty in producing
Despite this, the Foster-Seeley detector remains historically significant in the development of radio technology and is
