Post Subject: Taking ultrasound as an examplePosted by peter foster on: 8/5/2008
Dear Romy, taking ultrasound equipment as an example, there would appear to be much in common in the operation of ultrasound equipment as with a sound system. There is analog signal send/receive, conversion of analog signal received to digital form and then conversion of digital signal to analog for both video display AND audio (i.e., where you can hear the heartbeat of a foetus). My suspicion is that the devices used to supply power to such equipment must be rigorously constructed and would be optimized to a much higher standard for both audio and video, avoiding sonic problems and reliability problems of the poorly constructed equipment you are currently testing. Power supply equipment used for electron microscopes, presumably, would be of even a higher quality. There are second hand supplies of these equipments available on the markets so cost should be less. Even better, probably, would be the power supply equipment for submarine echo radar system (ping) where operators can distinguish craft and sea animals by sound. Perhaps one could obtain such a power supply equipment (second hand of course) from a dismantled submarine. With kind regards, Peter Foster.Rerurn to Romy the Cat's Site
