... need a long measuring time, whereas the PDC is much faster but can only measure up to about 1Hz. A new approach uses the advantage of both methods and measures the frequencies from 5kHz down to 0.1 Hz with the FDS and 0.1Hz down to 1mHz or even lower with the PDC. The PDC data are transformed into t ...

Examples of capacitors with suitable dielectrics include silver mica, polystyrene and ceramic NP0. The inductor, L1, must also be chosen for low RF losses (i.e. high ‘Q’). At th ...

Mathematics of radio engineering



The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
