iPower: Interactive Power Spectrum Demonstrator 2 Description
Description: Keyboard-controlled interactive power spectrum demonstrator, useful for teaching and learning about the power spectra of different types of signals and the effect of signal duration and sampling rate. Single keystrokes allow you to select the type of signal (12 different signals included), the total duration of the signal, the sampling rate, and the global variables f1 and f2 which are used in different ways in the different signals. When the Enter key is pressed, the signal (y) is sent to the Windows WAVE audio device. Press K to see a list of all the keyboard commands.
T. C. O'Haver (toh@umd.edu), version 1, May 2011

KEYBOARD CONTROLS:
Adjust signal duration 10% up/down......A,Z
Adjust sampling rate 10% up/down........S,X
Adjust first variable 10% up/down...... D,C
Adjust second variable 10% up/down..... F,V
Print keyboard commands...................K
Play signal as sound.............Enter or P

SIGNAL TYPES
` Sine wave, frequency f1 (Hz), phase f2
1 Square wave, frequency f1 (Hz), phase f2
2 Sawtooth wave, frequency Ff1(Hz)
3 Triangle wave, frequency f1 (Hz), phase f2
4 Sine wave burst of frequency f1 (Hz) and length f2 sec
5 440 Hz carrier amplitude modulated by sine wave, frequency f1 (Hz) and amplitude f2
6 440 Hz carrier frequency modulated by sine wave of frequency f1 (Hz) and amplitude f2
7 Sine wave, frequency f1 (Hz), modulated with Gaussian of width f2 sec
8 Sine wave, frequency f1 (Hz) with non-linear transfer function f2
9 Sine wave sweep from 0 to f1 (Hz)
0 Sine wave of frequency f1 (Hz) and amplitude f2 plus random white noise
- Pink (1/f) noise
= Sine wave, frequency f1 (Hz), amplitude f2 plus pink noise

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a...
