Abstract:
This Letter proposes an improved compressive-sensing-based methodology for aeroengine fan noise detection to guarantee the performance under low signal-to-noise ratio conditions. The principle behind the proposed method is to modify the mode power spectrum in a way with increased sparsity, which is demonstrated in both numerical studies and experimental validations. Overall, the proposed method could be applicable to aeroengine testing applications.

MOSFET: Enhancement Mode
In their basic form, enhancement-mode MOSFETs are typically non-conductive when the gate-source voltage (Vgs) is zero. This default 'off' state means no...
What is a Mode?
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...
