| + | Digital electronics provides utmost flexibility, reconfigurability and | ||
| + | long term stability when processing discrete time radiofrequency samples, | ||
| + | properties sought when analyzing ultra-stable oscillator properties. Also | ||
| + | known as software defined radio, digital processing of radiofrequency signals | ||
| + | requires a combination of multiple skills to achieve flexible and stable | ||
| + | instruments such as composite clocks, phase characterization bench and | ||
| + | closed controlled phase feedback loops. Because of the complexity of | ||
| + | adressing all fields related to digital electronics ranging from radiofrequency | ||
| + | signal acquisition (fast analog to digital conversion) and digital pre-processing | ||
| + | taken care of in FPGAs, to transferring to a general purpose processor (Linux | ||
| + | kernel space drivers) and implementing user space digital signal processing | ||
| + | algorithms, a dedicated library has been developed which is being released | ||
