Abstract

A versatile low cost analog to digital conversion unit built from commercially available components that connects to a standard PC or Notebook via the Universal Serial Bus was developed. With a sampling rate of 10kHz, 8 bit resolution and the potential for a large number of channels the system can be used for analog data acquisition in research, classroom and field environments. The A/D converter has been successfully used for the testing of gymnastics landing sunaces.
