At its simplest, a phase-locked loop is a closed-loop feedback control circuit that's both frequency- and phase-sensitive. A PLL is not a single component, but a system that consists of both analog and digital components -- interconnected in a "negative feedback" configuration. Consider it...
In the most fundamental sense, the term circuit refers to a physical or conceptual loop, often with an emphasis on resolving or closing that loop to accommodate various operations associated with electrical systems or other technologies. In IT, the term is often used when discussing the physical ...
Phase-locked loop (PLL)A phase-locked loop (PLL) is a feedback circuit designed to allow one circuit board to synchronize the phase of its on board clock with an external timing signal. PLL circuits operate by comparing the phase of an external signal to the phase of a clock signal ...
A series circuit is a type of electrical circuit in which the components are connected end-to-end in a single loop. The same current flows through each element in a series circuit, but the voltage drops across each component can be different. Understanding series circuits is fundamental for an...
The opposite of a short circuit is an open circuit. This is a circuit where the loop isn't fully connected (and therefore this isn't really a circuit at all). Unlike the short circuit above, nothing will get hurt by this "circuit", but your circuit won't work either. If you're ne...
a conditional statement is a programming construct that allows you to execute different code blocks based on a specific condition. conditional statements use logical operations to determine which code block to execute. what is a loop? a loop is a programming construct that allows you to repeat a...
What is the current through the battery? What does a transformer do to AC voltage? What is a nominal current? What is the function of fuse or circuit breaker in a circuit? What is the loop of Henle? What is an analog output?
The 4-20 mA current loop has been the standard for signal transmission and electronic control in control systems since the 1950's.
control theory and discuss how to analyze the stability and bandwidth of a DC-to-DC voltage control loop. It may help designers to deeply understand control loop, as well as calculate circuit parameters accurately and quickly instead of using trial and error when encountering control loop p...
The antenna effect of the ground loop can create surges, damaging the electronic components or circuit. Leakage currents flowing between devices sharing common ground produce detrimental effects on the components and measurement systems. There is a reduction in the dynamic range of digital sig...
