Abstract for Lecture #6 - (A) The Analog to Digital Converter (B) Speed of Sound Measurement with a Kundt's Tube


The analog to digital converter (ADC) is a device which converts analog voltages into digital numbers. Applications in experiments center around measuring one of the dependent (response) variables in a stimulus - response experiment.

The operation of the successive approximation ADC will be described. Considerations of response time, linearity and digitization error will be discussed. The operation of the ADC from LabVIEW is described.

The physics of the Kundt's tube is elucidated and the application of the Fabry-Perot model is presented.

To prepare for this lecture review the material in chapter with particular emphasis on the material that pertains to the ADC (sections 8.2.3,8.3, 8.4, 8.5 and 8.8 (pp. 334-339). The lecture notes are available next to the door to Prof. Callis' office, 204 Bagley.
