Firebird

This was done for a client cira 1998. They had a long pipe where at one end four transducers were pulsed with a user definable waveform and, at the other end, there were another four transducers that listened to the resulting sound pulse.

The project required a custom, 4 channel digital to analogue converter and a 4 channel analogue to digital converter built into a PCI interface card. The card was based on a Xilinx FPGA in the days where PCI was still in its infancy.

The software below was a Visual C++ project that communicated with the card enabling you to define the transmit waveform and record the resulting input  waveform.

It’s even got a picture of a very young Andy Whittaker  😀
