The canonical signed digit (CSD) coding is widely used in digital arithmetic operations due to its property that there is no adjacent nonzero digits in the encoded numbers. However, the benefits of the CSD coding may be faded because of the recursive conversion process from the binary representations. This paper presents a novel pseudo CSD coding method, which takes the merits of CSD, while simplifies...
A special vibration test method of quartz flexible accelerometer is explored in this paper, in order to investigate dynamic changes with vibration frequencies. Utilizing a vibration exciter, the vibration accelerometer signals are collected, which can be applied for the permutation entropy analysis. Firstly, three parameters of permutation entropy are selected by comparative analysis to solve its...
