Η ΧΡΗΣΗ ΤΗΣ ΔΙΑΜΟΡΦΩΣΗΣ Δ-Σ ΣΤΗ ΦΑΣΜΑΤΙΚΗ ΑΝΑΛΥΣΗ ΣΗΜΑΤΩΝ
… 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 …

Strain sensor using fiber bragg grating interrogation
… monitoring method by using optical spectrum analyzers (OSA). Although FBG has better strain sensitivity measurement, however there have some restriction to monitor by using OSA. The usage of OSA are very costly, bulky and has slow scanning speed. Therefore, research is conducted to …

Integration and testing of a digital transceiver for a dual frequency, pulse-doppler radar
… included laboratory signal generators, spectrum analyzers and oscilloscopes. The digital transceiver was able to function at pulse repetition rates exceeding 2 kHz, with a single transmit channel and three receive channels active. The lowpowered monostatic prototype system was …

Second Harmonic Generation Stimulated Electromagnetic Emissions during High Power High Frequency Radio Wave Interaction with the Ionosphere
… and the frequency resolution of receivers/spectrum analyzers of the time. Experimental observations from these past studies reported either SEEs produced as a result of SHG in isolation or compared these SEEs with PW- WSEEs. Moreover, these experiments did not evaluate effects such as …
