High noise levels can block, distort, change or interfere with the meaning of a message in human, animal and electronic communication. In signal processing or computing it can be considered random unwanted data without meaning; that is, data that is not being used to transmit a signal, but ...

In the transmitter, a 9-line 32-GHz spaced laser comb (centered at 1550 nm) is used as the phase-locked optical carrier for each sub-channel. Digital-to-analog convertor (DAC) with a resolution of 16-bit (to ensure no back-to-back implementation penalty) and root-raised- cosine (...
A filtering device (2) is coupled to an output of the noise shaper and is designed to reject radio-frequency signal components in the latter digital word. A conversion device (3) is connected to an output of the filtering device and converts the latter digital word into an analog signal....
Phase noise is a concern for all radio systems, but radar in particular can require phase noise performance at frequency offsets much closer to the carrier than a communication system.
This separate class of log amps, used in fiber-optic communication systems to measure optical power and control the gain of optical-mode amplifiers, only measures essentially static currents, from as low as 1 picoamp up to several milliamps. Alternatively, using external input resistors, voltages...
This paper considers the effects of noise and transmission delays in a phase-averaging mutual synchronization system. The basic analytical ideas are developed with respect to a two-station system which contains first-or second-order analog phase-lock loops. From the equation describing the phase erro...
