The analysis of electrical signals is
a fundamental problem for many
engineers and scientists. Even if the
immediate problem is not electrical,
the basic parameters of interest are
often changed into electrical signals
by means of transducers. Common
transducers include accelerometers
and load cells in mechanical work,
EEG electrodes and blood pressure
probes in biology and medicine, and
pH and conductivity probes in chemistry.
The rewards for transforming
physical parameters to electrical signals
are great, as many instruments
are available for the analysis of electrical
signals in the time, frequency
and modal domains. The powerful
measurement and analysis capabilities
of these instruments can lead to
rapid understanding of the system
under study.
