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 ...

2. Time-frequency representations of radar and communications waveforms. (© 1984–2019 The MathWorks, Inc.) These images are used to train a deep convolutional neural network (CNN).

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 ...

The 12 subcarriers were then combined in a linear mixer to form what was known as a basic group. Up to five basic groups could be further multiplexed on to higher-frequency subcarriers in the 312 ...

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