What is RF delay line?
What is RF delay line?
What are RF Delay Lines? A delay line is a device that delays the input signal by a certain amount of time. Delay Lines are used in a number of applications like radars, communication challen simulation, FM signal generation, signal processing etc.
What is a delay line circuit?
Delay lines are devices that introduce time delay to signals by a pre-determined time constant. They are characterized by their delay step, jitter performance and delay range.
Which circuit can be used as a digital delay line?
The most popularly used circuit as an electronic delay line is the monostable multivibrator.
How do you add a delay in an analog circuit?
There are several ways to introduce an analog delay into a signal channel. If you have enough room in your product, an appropriate length of coax cable can be introduced. Inductor-capacitor delay lines can be purchased.
What is delay line give the name of types of delay line?
There are two basic delay line types: fixed and variable. Fixed delay lines can delay signals by a time interval set by the manufacturer. For fixed delay lines, the delay time is the only delay time that can be set. Variable delay lines can delay signals between two values in a specified range.
What is the function of delay line?
The delay line is an elementary functional unit which models acoustic propagation delay. It is a fundamental building block of both delay-effects processors and digital-waveguide synthesis models. The function of a delay line is to introduce a time delay between its input and output, as shown in Fig.
How does a delay line work?
Delay lines were developed to store radar blips so that screens displayed only new, moving blips. In computers, delay lines converted data bits (ones and zeros) into sound waves, transmitted them acoustically, then converted them back into bits. They circulated forever until changed by the computer.
How do delay lines work?
Why is a delay line used in CRO?
The delay line is used to delay the signal for some time in the vertical section. When the delay line is not used, the part of the signal gets lost. Thus the input signal s not applied directly to the vertical plates but is delayed by some time.
How much delay the delay line has?
The delay line has a time delay equal to the pulse repetition interval. The received signal and the reference signal are fed to a mixer called the phase detector, whose output is proportional to the phase difference of the two input signals. The canceller output in the time domain is as follows: (10.37)
What is a programmable delay line?
What is a programmable delay line? A programmable delay line allows a user to programmatically specify and modify delay in a high frequency/RF signal path. This results in a signal delay, as measured in the time domain, or a phase shift, as measured in the frequency domain.
What is an optical delay line?
An Optical Delay Line is a method of wave guide where the media is fiber with a fixed index of refraction and relative constant group delay variation. There are various applications that can use ODL systems, such as radar range calibration, MTI (moving target indication), clutter canceller, BIT,…
What is an electronic delay line?
delay line. n. (Electronics) a device in which a known delay time is introduced in the transmission of a signal. An acoustic delay line delays a sound wave by circulating it through a liquid or solid medium.
