A digital delay line (or simply delay line, also called delay filter) is a discrete element in a digital filter, which allows a signal to be delayed by a number of samples. Delay lines are commonly used to delay audio signals feeding loudspeakers to compensate for the speed of sound in air, and to align video signals with accompanying audio ...
The Hammant & Morgan (H&M) digital train control system is totally compatible with the Zero 1, the master controller,"HM5000 Advanced Power Transmitter" boasted two sliders, direction LEDs, a power LED bar graph, timer clocks, digital display of locos under control, readout of accessories controlled, and ability to attach two "Hi-Tec Speed ...
While there are strictly analog [2] electronics circuit simulators, popular simulators often include both analog and event-driven digital simulation [3] capabilities, and are known as mixed-mode or mixed-signal simulators if they can simulate both simultaneously. [4] An entire mixed signal analysis can be driven from one integrated schematic ...
In the Control Systems jargon, the DLL is a loop one step lower in order and in type with respect to the PLL, because it lacks the 1/s factor in the controlled block: the delay line has a transfer function phase-out/phase-in that is just a constant, the VCO transfer function is instead G VCO /s. In the comparison made in the previous sentences ...
The simulator first divides the circuit into analog and digital portions. The analog circuitry is simulated with the time-step driven SPICE engine, while the digital parts are simulated separately with an event-driven simulation engine. The CircuitLogix digital engine was developed directly in .NET, faster than SPICE macros. Because the ...
PLECS includes the possibility to model controls and different physical domains (thermal, [2] magnetic [3] [4] and mechanical [5]) besides the electrical system. Most circuit simulation programs model switches as highly nonlinear elements. Due to steep voltage and current transient, the simulation becomes slow when switches are commutated. In ...
In order to increase accuracy (and decrease speed), the most common methods are: Lumped C. The entire wire capacitance is applied to the gate output, and the delay through the wire itself is ignored. Elmore delay [5] is a simple approximation, often used where speed of calculation is important but the delay through the wire itself cannot be ...
Märklin offered many different decoders and kits to upgrade analog locomotives to digital control. A digital decoder was the basis and many kits also included a permanent magnet and 5 pole armature to upgrade the motor and convert it to DC (such decoders rectify track current to DC for the motor and any accessories, such as lighting or sound).
