Atienza asks Malacanang to certify his House Bill 5360 installing the Benham or Philippine Rise Protection and Development Authority (PRPDA) "to guarantee that all natural resources within the 13 million-hectare undersea region are preserved for the exclusive enjoyment of future generations of Filipinos." The proposed bill assigns the socioeconomic planning secretary, who is also National Economic and Development Authority chief, to chair the PRPDA's governing board.
PD signals are monitored by a digital oscilloscope and are acquired by means of a bipolar PRPDA (Phase Resolved PD analyzer) system with 64 amplitude channels and 128 phase channels at fixed time intervals.
In the case of tests where the involved phenomena are time variant, the acquisition time must be set short enough to allow an approximation to a time invariant system during the acquisition stage, but it must be sufficiently long to obtain correct information from the PRPDA. In our case it has been set at 40 s.
