A series of resistor–capacitor circuits (RC circuits) can be cascaded to form a delay. A long transmission line can also provide a delay element. The delay time of an analog delay line may be only a few nanoseconds or several milliseconds, limited by the practical size of the physical medium used to delay the signal and the propagation speed ...
The first example gives the circuit for a 6th order maximally flat delay. Circuit values for z a and z b for a normalized lattice (with z b the dual of z a) were given earlier. However, in this example the alternative version of z b is used, so that an unbalanced alternative can be easily produced. The circuit is
The multi-trigger versions have programmable logic controller-type functionality for incorporating interlocks, latches, dynamic delay adjustment, and trigger noise suppression. Triggers are formed by logically combining the inputs and outputs in And, Or, Xor, and Negated forms. LIDAR applications use digital delay generators. A channel is used ...
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 ...
So finally, the bridged-T circuit takes the form Bridged-T circuits like these may be used in delay and phase-correcting networks. Another lattice configuration, containing resistors, is shown below. It has shunt resistors Ro across the Z a ’s and series resistors Ro as part of the Z b 's, as shown in the left hand figure. It is easily ...
In this example, because the filter has an unbalanced form, it is necessary to use bridged-T equivalents in the phase corrector, rather than lattice circuits. The phase corrector is shown below. As the phase corrector is an all-pass and constant resistance circuit, it does not change the amplitude response of the filter.

Example Ladder Logic Diagram. The schematic diagrams for relay logic circuits are often called line diagrams, because the inputs and outputs are essentially drawn in a series of lines. A relay logic circuit is an electrical network consisting of lines, or rungs, in which each line or rung must have continuity to enable the output device. A ...
