The phrase “delay line” refers to a technique used in (analogue) telecommunications to modify the time between various signals by delaying one of them.
Consider the luminance and chrominance channels on a color cathode ray tube television. It is called a line because that is all that it is: a wire. more frequently heard delay lines referred to as tapped delay lines in the discrete (digital) realm.
This is due to the fact that each sample introduces a delay, and in order to create a FIR filter, we must access (tap into) the signal at various delays. I would refer to the line of z1 boxes as a tapped delay line.
The original Dallas delay lines were made up of an RC-based ramp generator and a comparator circuit that, when a specific voltage level was reached on the ramp generator, switched the delay line output on. A laser was used to blow a sequence of fuses at the wafer level during calibration to create the appropriate delay. No provision was made for temperature compensation.
The Global delay line market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Delay-Line Contacts are single-element transducers that measure the thickness of thin-section materials and operate on longitudinal waves (straight beams). Stand-offs that can be replaced enhance near-surface resolution and prolong product life.
Probes for Delay-Lines that are Replaceable. For applications requiring a very small contact face, such as measuring the thickness of curved turbine blades or from the inside of a pit, pencil probes are created. They are compatible with the majority of fault finders and precise thickness gauges.
Tapered to tip sizes of 0.065 inch (1.7mm) and 0.090 inch, interchangeable delay lines are available (2.3mm). Packs of 10 replacement delay lines are offered. The straight model comes with a detachable handle that also functions as a fingertip probe. Microdot connections are available on all models.
To provide the required timing delays required to construct both delay lines and precision all-silicon oscillators, EconOscillators and delay lines both employ a compensated voltage-controlled delay line (VCDL) approach. The architecture employed in these devices is thoroughly described in this application brief. This architecture is used by the DS1100, DS1135, DS1110, DS1077, DS1085, and DS1086 among other devices.
Dallas Semiconductor was the first business to create the all-silicon delay line in the early 80s. This gave rise to a more compact, reasonably priced replacement for the existing modular delay lines.
The present generation of lines is more advanced than before. The voltage-controlled delay line (VCDL), used in conjunction with a compensation circuit to lessen delay fluctuations brought on by changes in process, temperature, and voltage, is a unique circuit found in Maxim/Dallas all-silicon delay lines.
A silicon delay line is simple to construct. Any logic gate can be utilized as a delay line because they all have propagation delays. Constructing a delay line that can be precisely adjusted to a certain delay period and stays constant despite changes in process, temperature, and voltage is challenging. An independent compensation strategy is necessary to stabilize these delay times.
The high-frequency Altimeter Optical Delay Line (ALT ODL), which RFOPTIC created to suit client demand, is a high-performance solution for calibrating and testing radar altimeter systems. The RFOptic family of optical delay lines includes the ALT ODL.
The ALT ODL unit from RFOptic is a small-footprint device that offers exceptional signal performance and altitude simulation accuracy while operating virtually silently. A single altitude or up to 4,096 altitude steps can be emulated using the ALT ODL.
For altitude steps under 6 feet and more than 0.1% above, the Altimeter ODL gives extremely high accuracy up to 0.3ns. In one enclosure, the greatest altitude can exceed 30 kilometers (Km) or 100,000 feet.
