Understanding Signals
-- Understanding Signals shows you how to generate, view, and measure a variety of wave forms with the Parallax USB Oscilloscope and BASIC Stamp®-controlled circuits. Each activity includes an example circuit and PBASIC code, directions for configuring the oscilloscope and placing the probes, and screen-captures of the Parallax USB Software interface displaying the signal.

Topics include:

Analog inputs from photoresistors and A/D converters

RC-time in resistor-capacitor networks

Asynchronous serial communication between the PC and a BASIC Stamp module

Synchronous serial communication between a BASIC Stamp and ADC0831 A/D converter

Single and dual sine waves

Servo pulse signals over an entire range of motion

Pulse width modulation with infrared

Decoding of handheld infrared remote control signals

Voltage amplification and inversion with DC offset with an op-amp

Running the experiments in this text requires the Parallax USB Oscilloscope and a Board of Education with a BASIC Stamp 2.

Also available:
Parallax USB Oscilloscope
Boe-Bot Robot Kit (Includes a USB-compatible Board of Education)

Understanding Signals is an integral part of ARRL's Teacher Institute on Wireless Technology
