SinusoidInNoise
This model measures the power spectrum of
bandlimited noise added to a sinusoid. The
spectrum is plotted together with the theoretical
value of the spectrum of the noise. Notice that
the sidebands decay slightly more slowly than
the theory predicts because of aliasing distortion.
You can experiment with the bandwidth of the
noise and the frequency and amplitude of the
sine wave.
SinusoidInNoise is available in two formats:
- As a Web Start Application:
- As an applet.
The Java Web Start version is preferred, though browsers with versions of Java
earlier than Java 1.6.0_13 may only work with the applet version.
See Web Start Help for details.
