Signalspektrum is a term used in signal processing and telecommunications to describe the distribution of signal power or amplitude over a range of frequencies. It essentially shows which frequencies are present in a signal and how strong they are. Think of it as a fingerprint of a signal, revealing its frequency components.

The signalspektrum is typically visualized as a graph where the horizontal axis represents frequency (often in Hertz, Hz) and the vertical axis represents the magnitude or power of the signal at that frequency. A signal with a narrow signalspektrum contains energy concentrated around a few specific frequencies, while a signal with a wide signalspektrum has energy spread across a broad range of frequencies.

Understanding the signalspektrum is crucial for various applications. In radio communication, it helps in allocating frequency bands to avoid interference. In audio engineering, it's used to analyze and equalize sound. In medical imaging, like MRI, it's essential for reconstructing images. Analyzing the signalspektrum allows engineers and scientists to identify, filter, and manipulate signals based on their frequency content. Techniques like the Fourier Transform are commonly used to compute the signalspektrum from a time-domain signal.
