Resumen
MACIAS-BOBADILLA, G. et al. Digital phase-analyzer for low frequency applications based on reconfigurable hardware. Superf. vacío [online]. 2010, vol.23, n.2, pp.14-18. ISSN 1665-3521.
In Photoacoustic experiments and low frequency Photodiode applications, Phase sensitive detection is one of the basic operations performed by a lock-in amplifier. Regrettably, it is common to use only basic functions of those devices, in spite of their high cost. The objective of this research is to show the results that were obtained from the development and design of a basic phase shift sensitive device using reconfigurable hardware, which allows a reduction in experimental costs while generating the possibility to apply the developed device in different research fields.
