It is possible to apply the modulation to a low power stage of the transmitter, and it is not necessary to use a linear form of amplification to increase the power level of the signal to its final ...

Linear Frequency Modulation (or FM synthesis for short) on the other hand starts with a sine-wave (containing only a fundamental pitch and no additional harmonic information), and adds harmonic ...

To achieve this it is normally necessary to allow a bandwidth equal to twice the maximum frequency of deviation plus the maximum modulation frequency. In other words, for a VHF FM broadcast station ...

Scientists at NPL recently published findings on laser frequency stabilization, demonstrating an unprecedented level of ...

There is a linear frequency modulation of the signal that chirps the carrier frequency from 300 MHz at the start of the RF pulse envelope to 900 MHz at the end of the pulse envelope.
