Analog delay lines are applied in many types of signal processing circuits; for example the PAL television standard uses an analog delay line to store an entire video scanline. Acoustic and electromechanical delay lines are used to provide a " reverberation " effect in musical instrument amplifiers, or to simulate an echo.
The internal block diagram and schematic of the 555 timer are highlighted with the same color across all three drawings to clarify how the chip is implemented: [2] Voltage divider : Between the positive supply voltage V CC and the ground GND is a voltage divider consisting of three identical resistors (5 kΩ for bipolar timers, 100 kΩ or ...
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 ...
VOX circuitry usually has a front panel adjustable delay that can be used to control the length of time it takes for T/R switches to operate but generally the delay adjustment range is limited to that of human voice syllables and, although automatic, is generally not fast enough to act in the short periods between Morse code dots and dashes.
The initial formulation of the retiming problem as described by Leiserson and Saxe is as follows. Given a directed graph:= (,) whose vertices represent logic gates or combinational delay elements in a circuit, assume there is a directed edge := (,) between two elements that are connected directly or through one or more registers.

From here, it can be easily seen that adding more inverters to the chain increases the total gate delay, reducing the frequency of oscillation. The ring oscillator is a member of the class of time-delay oscillators. A time-delay oscillator consists of an inverting amplifier with a delay element between the amplifier output and its input.
But the main draw is the customization. Inside the included carrying case, the Elite Series 2 has six different thumbsticks, four rear paddle buttons, and two different D-pads.
