Fast signal generator

The goal of the project is to propose a way for faster calibration of Xampling system (by Moshe Mishali). The project explores two different approaches, one by finding an appropriate model for analog frequency mixer and merging it in software calibration process, the other – by creating LabView scripts for automating hardware calibration. The second approach proved to be successful.

Sub-Nyquist Sampling – A/D module

The project’s goal is to integrate a sub-system that would convert the incoming analog samples to digital signals. Then they will be processed and reconstructed in the sub-Nyquist Sampling system.

Sub-Nyquist Ultrasound

Ultrasound imaging requires large amount of data to be collected and processed. New studies try to reduce the amount of data by using Sub-Nyquist techniques. The project continues this work and suggest a new digital processing method which greatly improves image quality and computation complexity.
