2. Signal processing - Wikipedia

   en.wikipedia.org/wiki/Signal_processing

   Signal processing is an electrical engineering subfield that focuses on analyzing, modifying and synthesizing signals, such as sound, images, potential fields, seismic signals, altimetry processing, and scientific measurements. [1] Signal processing techniques are used to optimize transmissions, digital storage efficiency, correcting distorted ...

3. Spectral density estimation - Wikipedia

   en.wikipedia.org/wiki/Spectral_density_estimation

   Spectral density estimation. In statistical signal processing, the goal of spectral density estimation (SDE) or simply spectral estimation is to estimate the spectral density (also known as the power spectral density) of a signal from a sequence of time samples of the signal. [1] Intuitively speaking, the spectral density characterizes the ...

4. Estimation theory - Wikipedia

   en.wikipedia.org/wiki/Estimation_theory

   Estimation theory. Estimation theory is a branch of statistics that deals with estimating the values of parameters based on measured empirical data that has a random component. The parameters describe an underlying physical setting in such a way that their value affects the distribution of the measured data. An estimator attempts to approximate ...

   The following terms are used by electrical engineers in statistical signal processing studies instead of typical statistician's terms. Statistics. Electrical engineering. Null hypothesis. Noise only hypothesis. Alternative hypothesis. Signal + noise hypothesis. Critical region. Signal present decision region.

6. Statistical process control - Wikipedia

   en.wikipedia.org/wiki/Statistical_process_control

   Statistical process control (SPC) or statistical quality control (SQC) is the application of statistical methods to monitor and control the quality of a production process. This helps to ensure that the process operates efficiently, producing more specification-conforming products with less waste scrap. SPC can be applied to any process where ...

7. Undersampling - Wikipedia

   en.wikipedia.org/wiki/Undersampling

   Undersampling. Fig 1: The top 2 graphs depict Fourier transforms of 2 different functions that produce the same results when sampled at a particular rate. The baseband function is sampled faster than its Nyquist rate, and the bandpass function is undersampled, effectively converting it to baseband. The lower graphs indicate how identical ...
