Sammanfattning
How accurately can we measure a high-frequency signal? The frequency resolution that can be achieved with standard analog circuits or microwave cavities is about 1Hz for a MHz signal and 1kHz for a GHz signal. However, this frequency resolution is not enough in some applications within the fields of digital spectroscopy or radar technology. So, can we do better? Well, research at Lund University shows a promising new measurement technique that theoretically can measure a high-frequency signal with arbitrary precision. The new technique is based on high-speed digitizers collecting data from a high-frequency signal which is processed through an algorithm which mimics the behavior of a digital cavity. In this way high-frequency signals can be measured with extreme precision. The research in this field, which this master thesis work will be a part of, is focused on building prototype device(s) for precision measurement of GHz signals, with the intention of being used in mission critical applications like radar technology, aviation technology and other high-end devices for digital spectroscopy, clock synchronization, wireless communication, etc. The goal of the master thesis project is mainly to verify and to “prove the concept” of the new measurement technology. A secondary goal with the master thesis project is to prepare the measurement technology for commercialization. Having close contact with industry will therefore be important during the project.
