Introduction In this lab investigation, the main focus was on transducers and their applications. In particular, we looked at two types of transducers, sound and temperature via a speaker and a thermistor respectively. As defined in the lab manual, a transducer converts some physical aspect, in our case sound and temperature, into an electrical signal. Input signal transducers convert physical aspects into electrical signals, and output signal transducers convert the other way around. In the analysis of the first system consisting of a sound input transducer via a speaker, a transfer function response curve was plotted to observe its characteristic transfer curve. In the second example, an introduction to thermistors is conducted. Thermistors are semiconducters that demonstrate a corresponding resistance as the temperature fluctuates. Therefore, an electrical signal relationship can be observed and deduced as the temperature is changed.
