Pulshöjd

Pulshöjd, often translated as pulse height, is a fundamental concept in signal processing, particularly in applications involving the detection of particles or events. It refers to the maximum amplitude or peak voltage of a signal pulse generated by a detector. When a particle interacts with a detector material, it typically deposits energy, which in turn produces an electrical signal. The magnitude of this signal, and thus its pulshöjd, is often proportional to the energy deposited by the particle.

In many detection systems, such as those used in nuclear physics, radiation detection, or medical imaging, the pulshöjd is a crucial parameter for distinguishing between different types of events or particles. By measuring the pulshöjd, one can infer information about the energy of the incident particle. For instance, a higher pulshöjd would indicate a higher energy deposition. This principle allows for energy spectroscopy, where detectors are used to measure the energy distribution of incoming particles.

The pulshöjd is also influenced by factors such as the detector's intrinsic properties, the detector's electronics, and the interaction volume of the particle. Variations in these factors can lead to a spread in pulshöjd for particles of the same energy, a phenomenon known as energy resolution. Therefore, careful calibration and understanding of these influences are essential for accurate measurements. Techniques like pulse shaping and amplification are employed to optimize the measurement of pulshöjd.
