JSON data is written inkey/valuepairs. The key and value are separated by a colon(:) in the middle with the key on the left and the value on the right. Different key/value pairs are separated by a comma(,). The key is a string surrounded by double quotation marks for example “name...
methods are FFT [9], [12], STFT [41], Hilbert-Huang Transform (HHT) [11], DWT [28], [40] and absolute value-based principal component analysis (AVB-PCA) [15], which suffer from unstable Q-factor, whereas, in the proposed method RDWT (constant Q-factor) is utilized for signal ...
