distorsioprodukti
Distorsioprodukti, commonly translated as distortion products, are additional signals generated when a nonlinear system is driven by two or more input frequencies. In electronic circuits, nonlinearities in components such as transistors, diodes, or op‑amps produce intermodulation distortion products at frequencies that are linear combinations of the original tones: f_i ± f_j, 2f_i ± f_j, and so on. These products are often unwanted because they degrade audio fidelity, reduce signal‑to‑noise ratio, and can interfere with adjacent channels in communication systems.
In sensor technology, distortion products are exploited for diagnostic purposes. For example, in otoacoustic emissions testing
Similarly, in magnetic resonance imaging, nonlinearities in gradient coils can produce distortion artifacts, and imaging sequences
Mathematically, the distortion products arise from the Taylor series expansion of the system’s transfer function. The
In summary, distorsioprodukti are a fundamental phenomenon in many branches of science and engineering, highlighting the
