invented by
Reginald Fessenden around 1900. An AM
radio signal can be
demodulated by
rectifying it to
remove one side of the carrier, and then filtering...
- The hot-wire
barretter was a
demodulating detector,
invented in 1902 by
Reginald Fessenden, that
found limited use in
early radio receivers. In effect...
- Frequency-shift
keying (FSK) is a
frequency modulation scheme in
which digital information is
encoded on a
carrier signal by
periodically shifting the...
- usage,
surface acoustic wave (SAW)
devices are
often used to
generate and
demodulate the
chirped signals. In optics,
ultrashort laser pulses also
exhibit chirp...
-
advanced receivers can
demodulate multiple layers. For a user with a
conventional receiver or poor reception, it may only
demodulate the data
stream embedded...

Envelope detectors can be used to
demodulate an
amplitude modulated (AM) signal. Such a
device is
often used to
demodulate AM
radio signals because the envelope...
- DRM and
analogue radios can
receive a
signal they can
discriminate and
demodulate, with
little disadvantage to
either mode. It can, however,
decrease DRM...

- NTSC. For this reason, to mix two
SECAM signals, they must be
demodulated, the
demodulated signals mixed, and are
remodulated again. Hence, post-production...
