What is RF delay lines?
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 are the two types of delay lines?
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 delay line in electronics?
delay line An electronic device that produces a finite accurate time delay between a signal imposed on its input and the appearance of the same signal at its output. These devices may be used as short-term signal stores or to provide accurate delays in signal-processing circuits.
How many delay lines are used by Cro?
There are two types of delay lines used with CROs. The lumped parameter delay line and the distributed parameter delay line, are the two types. A block diagram showing the position of the delay line is given below.
Why delay line is introduced in MTI system?
As the name suggests, delay line introduces a certain amount of delay. So, the delay line is mainly used in Delay line canceller in order to introduce a delay of pulse repetition time. Delay line canceller is a filter, which eliminates the DC components of echo signals received from stationary targets.
Why is a delay line used in a CRO *?
A delay line is used in an oscilloscope to view the leading edge of the trigger event. The trigger signal is usually derived from the vertical signal path. A delay line placed in the vertical signal path after the trigger signal will result in the ability to display the trigger portion of the signal.
What is the purpose 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.
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.
