Radio Frequency (RF) Spectrum Analyzers
An RF spectrum analyzer allows one to view the frequency components of an RF
signal. For example, one can view the spectral components of an AM signal, which

includes the carrier and any of the AM signars sidebands.
Fortunately, this book will not require any RF spectrum analyzers. But one can
download a program from the Internet to convert your com puter into a
low-frequency (e.g., 1 Hz to 22 kHz for a 44.1 kHz sampling rate, or 1 Hz to 48 kHz
for a 96 kHz sampling rate) spectrum analyzer. For example, download the

Spectran program from the web at http://digilander.libero.it/i2phd/spectran.html.
