Chapter 3:Signals and Systems¶

Introduction¶

Materials and Devices is concerned with how semiconductor devices, such as transistors, diodes, and sensors work and how they are built. Introductory courses cover the physics and properties of electronic materials: semiconductors, metals and insulators, and how these materials are combined to form electronic devices. Higher level courses specialize in particular areas such as optoelectronics, semiconductor processing, magnetics, or sensors. In the undergraduate semiconductor fabrication laboratory, students learn to use semiconductor processing equipment in the clean room to fabricate and test their own diodes and transistors.

Section Overview¶

This lab uses the Teensy in a simple circuit that acts like a piano. Using a variable resistor as input, an attached speaker will produce at least an octave of distinct musical notes. Later in the lab, application programming (programming for a computer) is used to interface with the embedded programming (programming for a device with hardware, like the Teensy2.0) to create a song composer program.
