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...

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...
- The hot-wire
barretter was a
demodulating detector,
invented in 1902 by
Reginald Fessenden, that
found limited use in
early radio receivers. In effect...
- DRM and
analogue radios can
receive a
signal they can
discriminate and
demodulate, with
little disadvantage to
either mode. It can, however,
decrease DRM...

includes in its
solution for 18 to...
- Frequency-shift
keying (FSK) is a
frequency modulation scheme in
which digital information is
encoded on a
carrier signal by
periodically shifting the...
- sent simultaneously, in parallel. At the receiver, the
carriers are
demodulated and the bits are
combined in the
proper order into one bitstream. Many...

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