For training objectives, we used L1 and multi-resolution STFT loss as follows: Ltotal(x,x^)=1T[‖x−x^‖1+∑m=1MLstft(m)(x,x^)] where the multi-resolution STFT loss is the sum of the STFT losses, which is the sum of the spectral convergence (sc) and magnitude (mag) loss,...
The frequency resolution is the minimum frequency interval that can be distinguished by certain algorithm. 频率分辨率是指所采用的算法能够被识别的两个单音信号的最小频率间隔,在实际测量中,通常根据频率分辨率确定所需要的最小采样点数。 3. The frequency resolution and the character of real-time are also ...
busy so that he couldn't do any reading.So he gave up his job and opened a bookshop in the center of the town.It wasn't big but all the books were nice and most people liked to buy some there.When the shop was closed,he could read at home.He knew a lot and many learne 先生...
we introduce a spectral estimator enabling time-frequency super-resolution, called superlet, that uses sets of wavelets with increasingly constrained bandwidth. These are combined geometrically in order to maintain the good temporal resolution of single wavelets and gain frequency resolution in upper ban...
1.New standard of resolution in time and frequency is required.对时间分辨率和频率分辨率提出了新的要求。 2.In the end, we introduce several main applications of a time reversal mirror and some new methods with TRM.时间反转镜的时间分辨率和空间分辨率与很多因素有关。 3.Transcoding Based on Reducing...
By using highQresonators and a final active quenching of the oscillation, it is possible to conjugate high time resolution and a small measurement time, which allows a high measurement rate. Methods for fast analysis of the data are considered and discussed with reference to computing resource ...
By incorporating the wavelet analysis into the FTP task, a time-frequency perspective is provided to perform the pattern recognition for different time and frequency scales, making it highly effective for multi-resolution analysis to enhance the FTP performance. In addition, the proposed approach also...
The multi resolution time domain method (MRTD) is employed to analyze the dispersion curves of 2 D dielectric PBG structure. 采用时域多分辨率法分析计算了在TM波情形下二维介质光子带隙结构的色散曲线 。5) optimum time-frequency resolution 最优时频分辨率 1. In order to improve time-frequency reso...
