Digital signal source

The Digital signal source allows us to set a single wire to any bit sequence in time. To get this part, type P, and then enter the name Digital signal ... 

Digital Signal Processor board fPSP) it is hosted into the PC and processes in real time the binary sequences stored into the acquisition board FIFO memories. The board processes arrival times and extracts the correlated AT generated by AE events. The PC picks up the data stored into the DSP memories and calculates the position of the AE sources. 

Some of the earliest digital signal processing work for audio restoration involved deconvolution for enhancement of a solo voice (Camso) from an acoustically recorded source (see Miller [Miller, 1973] and Stockham et al. [Stockham et al., 1975]). Since then, research groups at Cambridge, Le Mans, Paris and elsewhere have worked in the...
