DSP Board

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

DSP - Handles communications with the computer, controls all the activity of various components on the board, provides certain stages in signal processing.

Pulser - Sends a short electrical pulse to the transducer.

Receiver - Receives electrical signals coming back from the transducer.

Multiplexer - Redirects signals from pulser to a particular element in the transducer.

ADC (Analog-to-digital converter) - Converts electrical signals into a digital form.
