Digital signals and systems
(2017-01-31)
A causal system is one in which the output y(n) at time n depends only on the current input x(n) at time n, its past input sample values such as x(n-1), x(n-2), : Otherwise, if a system output depends on the future input ...
Pedestrian signalization and the risk of pedestrian-motor vehicle collisions in Lima, Peru
(Elsevier, 2014)
Safe walking environments are essential for protecting pedestrians and promoting physical activity. In Peru, pedestrians comprise over three-quarters of road fatality victims. Pedestrian signalization plays an important ...
Signal-flow graphs: Direct method of reduction and MATLAB implementation
(Institute of Electrical and Electronics Engineers (IEEE), 2001-05-01)
Block diagrams and signal-flow graphs are used to represent and to obtain the transfer function of interconnected systems. The reduction of signal-flow graphs is considered simpler than the reduction of block diagrams for ...

Digital signal processing of acoustic emission signals using power spectral density and counts statistic applied to single-point dressing operation
(Inst Engineering Technology-iet, 2017-08-01)
Dressing is an important operation for the grinding process. Its goal is to recondition the wheel tool to re-establish its cutting characteristics, owing to the wear produced after successive passes. Monitoring systems ...
Pitch detection algorithms based on zero-cross rate and autocorrelation function for musical notes
(2008-09-22)
This paper discusses two pitch detection algorithms (PDA) for simple audio signals which are based on zero-cross rate (ZCR) and autocorrelation function (ACF). As it is well known, pitch detection methods based on ZCR and ...
