It incorporated a left minus right component which was frequency modulated by about 1 kHz.
TV and FM (frequency modulated ) radio transmitter stations as well as transposer stations are almost always built on top of hills.
In signal processing a pulse or finite wavetrain can be considered as a signal of a single frequency modulated by an envelope, or as a superposition of an infinite number of infinitesimal waves of different frequencies.
In telecommunication, Carson's bandwidth rule defines the approximate bandwidth requirements of communications system components for a carrier signal that is frequency modulated by a continuous or broad spectrum of frequencies rather than a single frequency.
Waste gas from the chemical decomposition of the fuel is then used to create an FMCW (frequency modulated continuous wave) acoustic ranging signal that is Doppler insensitive (used for obstacle avoidance).
In these systems a "carrier" radar signal is frequency modulated in a predictable way, typically varying up and down with a sine wave or sawtooth pattern at audio frequencies.
It is the first private FM (frequency modulated) community radio station in Kerala.
The resulting CTCM signal was frequency modulated and combined with the FM audio carriers before it was written to the C track.
A stable oscillator that is frequency modulated is used to create the pulse rate because of this PFM is not as widely used.
The units may be frequency modulated (i.e., the pitch of the sound may go up, down, or stay the same during the note) or amplitude modulated (get louder or quieter).
