Störunterdrückungsverfahren

Störunterdrückung refers to the deliberate reduction or elimination of unwanted noise or interference in a signal. This process is crucial in various fields, including telecommunications, audio engineering, and medical imaging, to ensure the clarity and integrity of the desired information. The type of interference and the signal medium dictate the specific methods employed for Störunterdrückung.

In audio systems, Störunterdrückung might involve employing filters to remove background hum or hiss from recordings. Digital signal processing techniques are often used to analyze the signal and identify the characteristics of the noise, allowing for its targeted removal without significantly degrading the original audio. Similarly, in radio communication, techniques like noise cancellation are implemented to minimize external interference that can disrupt transmissions.

In medical imaging, such as MRI or CT scans, Störunterdrückung is vital for obtaining accurate diagnostic images. Artifacts caused by patient movement or external electromagnetic fields can obscure important details. Sophisticated algorithms are applied to preprocess the raw data and suppress these unwanted artifacts, leading to clearer and more reliable medical images. The goal of Störunterdrückung is always to enhance the signal-to-noise ratio, making the desired signal more discernible and useful.
