demodulerede

Demodulerede is the form used in Danish to describe something that has undergone demodulation. It is the past tense and past participle of the verb demodulere, which means to demodulate. In electronics, telecommunications and signal processing, demodulation is the process of extracting the original information signal from a modulated carrier signal. The term demodulerede is commonly used to describe signals, data streams or measurements that have been recovered or processed by a demodulation step.

Demodulation is the reverse operation of modulation. A modulated carrier carries information, and demodulation aims to recover the baseband or information signal from that carrier. The characteristics of the demodulerede signal depend on the modulation scheme, the channel, and the receiver design. In practice, different methods are used for different schemes, and the quality of the demodulerede output is influenced by noise, distortion and synchronization.

Common demodulation methods include envelope detection for amplitude modulation (AM), frequency discrimination or phase-locked loop techniques for frequency modulation (FM) and quadrature demodulation for phase modulation (PM). In digital communications, demodulation often involves coherent or non-coherent detection of symbols such as BPSK, QPSK or QAM, followed by symbol decision and decoding. The term demodulerede thus denotes the end result of the demodulation process: the recovered information signal or data.
