If you want to use one of the ultrasound gate you must buy an analogic micr=
ophone and connect it to a analog to digital converter and this one is conn=
ected via USB to a PC. Ultramic200K is fully integrated, in a tube 135 mm l=
ong and a diameter of 20 mm you have a MEM microphone (the same of this: ht=
tp://www.ultrasoundgate.com/knowlesspm.htm 420~450 euros) and the USB inter=
face. Internally there are an analog to digital converter 16 bit x 200K sam=
ple per second and the microcontroller that drive the USB interface.
