An ordinary PC with a
16-bit sound card is
turned into an excellent
audio-frequency measurlng
system, at a very
small outlay, just by
running some clever
software. Applications
of the PC-controlled AF
analyser include measuring
frequency and
phase response of
amplifiers, filters and, in
particular, loudspeaker I cross-overs. But that's
not all because the
analyser also enables
you to determine the
impedance of loudspeakers,
the inductance of coils, or the capacitance of capacitors.
A noticeable feaure
of the analyser is
its wide measuring
range, for instance,
from 50pH to 100pH
for inductors, and
100 pF to 100,000pF
for capacitors.
