reference signal वाक्य

Continuous wave radar systems rely on the Doppler effect to detect moving targets, comparing returned signals to the reference signal being broadcast.
In order to separate this low level signal from random noise a lock-in technique is used wherein a modulated voltage reference signal,
A part of the reference signal is detected and used as a video range tracking signal and as the video scope display.
Frequency multiplication can also be attained by locking the VCO output to the " N " th harmonic of the reference signal.
The NTSC signal includes a short sample of this reference signal, known as the colorburst, located on the'back porch'of each horizontal synchronization pulse.

For single carrier modulations, P reference is, by convention, the power of the outermost ( highest power ) point in the reference signal constellation.
In the artificial systems that are specified by engineering control theory, the reference signal is considered to be an external input to the'plant '.
This formula means that the output signal to interference ratio at a particular frequency is the reciprocal of the reference signal to interference ratio.
However in the Bloodhound's case the missile was moving away from the reference signal as fast, or faster than, the target would be approaching it.
Instead, they could be used for signal analysis by feeding a reference signal into one axis and the signal to measure into the other axis.
