DSP Board

The DSP (Digital Signal Processing) Board connects the transducer with the computer. The major parts of the board are:

Handles communications with the computer, controls all the activity of various components on the board, provides certain stages in signal processing
Sends a short electrical pulse to the transducer.
Receives electrical signals coming back from the transducer.
Redirects signals from pulser to a particular element in the transducer.
ADC (Analog-to-digital converter)
Converts electrical signals into a digital form.
