This work describes a relatively simple yet effective method for analyzing harmonic distortions and spectral analysis of electronic signals up to the MHz range. The method involves the use a suitable analog or digital oscilloscopes to present the signal, taking a digital picture of the...

Scientific, technical and economical feasibility of using water as an effective storage medium of solar energy generated by photovoltaic (PV) method is presented. The idea is based on using PV modules to generate electricity, and using this electricity to re-pump water from the outlet of an...
