Demodulasjonskvalitet

Demodulasjonskvalitet refers to the accuracy and fidelity with which a demodulator reconstructs the original information signal from a received modulated signal. In essence, it measures how well the demodulator can strip away the carrier wave and extract the intended message. A high demodulasjonskvalitet means the recovered signal is very close to the original, with minimal distortion or noise introduced during the demodulation process. Conversely, low demodulasjonskvalitet implies that the extracted signal is corrupted, leading to errors or degradation of the information.

Factors influencing demodulasjonskvalitet include the quality of the demodulator circuit itself, the presence of noise and interference in the transmission channel, and the characteristics of the modulation scheme used. Different demodulation techniques, such as coherent or non-coherent demodulation, can also have varying impacts on the resulting signal quality. Metrics like signal-to-noise ratio (SNR) at the demodulator's output are often used to quantitatively assess demodulasjonskvalitet. Poor demodulasjonskvalitet can manifest as static, garbled audio, or corrupted data in communication systems.
