Η ΧΡΗΣΗ ΤΗΣ ΔΙΑΜΟΡΦΩΣΗΣ Δ-Σ ΣΤΗ ΦΑΣΜΑΤΙΚΗ ΑΝΑΛΥΣΗ ΣΗΜΑΤΩΝ

THE PURPOSE OF THE PRESENT THESIS IS TO PROVE THAT THE USE OF Δ- Σ MODULATION LEADS TO VERY SIMPLE CIRCUITRY SPECTRUM ANALYZERS FOR AUDIO SIGNALS. TWO SPECTRUM ANALYZERS ARE PROPOSED: A HYBRID AND A DIGITAL ONE. IN THE FORMER SOME OPERATIONS ARE REALIZED BY ANALOG AND SOME OTHERS BY DIGITAL METHODS, WHILE IN THE LATTER ALL THE OPERATIONS ARE DIGITALLY PERFORMED. THE ANALYZERS ARE TESTED, IN ORDER TO VERIFY THEIR RESPONSE BESIDES THE SIGNAL TO NOISE RATIO, THE RESOLUTIONAND THE SENSITIVITY ARE THEORETICALLY DETERMINED AND EXPERIMENTALLY VERIFIED.
