Fourier transform of acquired signal
4
Filtering and Temperature
This is lab 4 of 10 in the course
Learn how to filter a signal in hardware and software then create a digital thermometer. In this project students acquire temperature data using a thermistor and take a Fourier transform of that data. They then implement a physical low-pass filter and a low-pass filter in software and observe the effects of each of these on the signal. Finally, students can take the data acquired from the thermistor to create a digital thermometer displaying temperature.
