Digital phase-locked loop (
DPLL) is a digital closed-loop automatic control system that can follow the frequency and phase of the input signals [7, 8].
This paper considers the DPLL(T) framework, which is extended from
DPLL and has been widely used in state-of-the-art SMT solvers.
By developing intra symbol frequency-domain averaging (ISFA) and digital phase-locked loop (
DPLL) as an improved channel estimation method, 42.13 Gbit/s 16QAM-OFDM signals at 86 GHz are successfully transmitted over 0.6 m air distance.
A timing card accepts references from multiple sources, selects one, cleans it from phase noise with a digital phase locked loop (
DPLL), and distributes it to the line cards via the backplane.
An example and a complete Mathcad set of design and analysis equations for a second-order type 2 digital PLL (
DPLL) are shown in Appendix A.
A new digital phase lock loop (
DPLL) was developed to recover the time-varying ground surface velocity from the output of a laser Doppler vibrometer (LDV) used in landmine detection.
In the self-synchronizing digital communication system, the methods to extract the bit synchronized signal mainly includes filtering method, enveloping "collapse" method, and
DPLL (Digital Phase-Locked Loop) method.
"Native" answer set solvers such as Smodels, [Smodels.sub.cc], and DLV are based on specialized search procedures in the spirit of the classic backtrack-search Davis-Putnam-Logemann-Loveland (
DPLL) algorithm.
For example, a two-stage carrier recovery parallel architecture based on a low-latency parallel
DPLL and the feedforward VV CPR algorithm has been proposed in [17].
State-of-the-art solvers extend the original Davis, Putnam, Logemann, and Loveland (
DPLL) procedure (Davis, Logemann, and Loveland 1962) with conflict analysis (Zhang et al.
