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...
- Frequency-shift
keying (FSK) is a
frequency modulation scheme in
which digital information is
encoded on a
carrier signal by
periodically shifting the...
- may be
demodulated in the same way as for non-differential PSK but the
phase ambiguities can be ignored. Thus, each
received symbol is
demodulated to one...
- together. At the receiver, the two
waves can be
coherently separated (
demodulated)
because of
their orthogonality.
Another key
property is that the modulations...

suppressed carrier. A
signal demodulated with a
product detector will have a
higher signal-to-noise
ratio than the same
signal demodulated with an
envelope detector...

demodulated. The
demodulated control signals are
transported over the IP

- A
receiver demodulated the
signal so that
sound picked up by the
microphone could be heard, just as an
ordinary radio receiver demodulates radio signals...
- some
modern satellites use on-board processing,
where the
signal is
demodulated, decoded, re-encoded and
modulated aboard the satellite. This type, called...
