Detection, Distortion, and Channel
Characterization
Detection is the measurement of specific signal components including DC, tones, and
noise. Detection and distortion measurements quantify linear and non-linear components of a
signal. Channel characterization measurements quantify the quality of the signal path, or the
channel. Channel characterization often compares detected signal components with a reference,
such as a known excitation amplitude, full scale, or the same signal components on a reference
signal or channel.
The following table shows different measurements in detection, distortion, and channel
characterization:
