10.1.2 Frequency Response of a Filter Digital filters represent linear transformations of time series. In order to understand specifically what occurs in the transformation, it is useful to consider the process in the frequency domain. The frequency response of a filter indicates the transformation th...

Based on the FFT of a single-tone sequence,this paper presents a novel Moving Average Maximum Likelihood (MAML) frequency estimator,which develops a Moving Average (MA) model by the real part relationship between different significant FFT coefficients firstly and a MA model-based maximum likelihood...
ROVX is between −27.024 and 37.249 with an average of 0.015 and a standard deviation of 2.298. Finally, RVIX has a minimum value of −13.022 and a maximum value of 33.364. The average and the standard deviation are 0.013 and 2.977, respectively. In addition to this, the summary ...
Resonance, in physics, relatively large selective response of an object or a system that vibrates in step or phase, with an externally applied oscillatory force. Resonance was first investigated in acoustical systems such as musical instruments and the h
According to the Nyquist sampling theorem, the reasonable acquisition frequency is defined as twice the cutoff frequency of the structural response [19], as shown in Figure 1. Figure 1. General amplifier or filter frequency response curve. The traditional cutoff frequency selection process is that...

Convolution equalizer is the most powerful type of equalizer software. These equalizers allow extremely precise control over the frequency response and the results are the same on all devices and platforms when using the same FIR filter. AutoEq supports convolution equalizers with FIR filters as WAV ...
Peri-stimulus time histograms (PSTH) of neuronal responses were constructed for every single cortical neuron identified in each subject. Neuronal data was binned using a sliding 10 ms time-window, smoothed using a 5-point moving average filter, and a method based on cumulative summed spike coun...
