Then their state can be read by an encoder to determine the delay. In general a digital delay-line based TDC, [19] also known as tapped delay line, contains a chain of cells (e.g. using D-latches in the figure) with well defined delay times . The start signal propagates through this chain and is successively delayed by each cell.
A direct form discrete-time FIR filter of order N.The top part is an N-stage delay line with N + 1 taps. Each unit delay is a z −1 operator in Z-transform notation. A lattice-form discrete-time FIR filter of order N.
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 rating of a brushless motor is the ratio of the motor's unloaded rotational speed (measured in RPM) to the peak (not RMS) voltage on the wires connected to the coils (the back EMF). For example, an unloaded motor of K v {\displaystyle K_{\text{v}}} = 5,700 rpm/V supplied with 11.1 V will run at a nominal speed of 63,270 rpm (= 5,700 rpm/V ...
The pulses on the coupled line that travel in the opposite direction to the pulse on the main line are also of opposite polarity to each other but the second impulse is delayed by twice the delay of the parallel line. For a λ/4 coupled-line the total delay length is λ/2 so the second signal is inverted and this gives a maximum response on the ...
Dynamic (electrical overhead-)line rating is a great opportunity for transmission line operators (any voltage from 15 kV to 735 kV and over). It has been studied for more than 20 years inside CIGRE and IEEE working groups.
The Smith predictor (invented by O. J. M. Smith in 1957) is a type of predictive controller designed to control systems with a significant feedback time delay. The idea can be illustrated as follows. Suppose the plant consists of () followed by a pure time delay .
The adaptive linear combiner (ALC) resembles the adaptive tapped delay line FIR filter except that there is no assumed relationship between the X values. If the X values were from the outputs of a tapped delay line, then the combination of tapped delay line and ALC would comprise an adaptive filter.
